 General keywords:
    after=time
      UNIX systems only.
      Hold execution until the specified time.  Also used by "submit".  See
      the at(1) man page for further information.  There is no default for
      this value.
    append={"yes","no"}
      Concatenate the F06, F04, and LOG files.  The file type of the
      concatenated file is "out".  The default is "append=no".
    batch={"yes","no"}
      UNIX systems only.
      Execute in background.  Overridden by "aft" and "queue".  The default is
      "batch=yes".  If running in an NQS/NQE batch job, the default is
      "batch=no".
    delete={"yes","no","all","jid",type}
      Comma-separated list of MSC.Nastran output file types to delete at job
      completion.  (For UNIX systems, the file type specification is
      case-sensitive.)  "delete=yes" is equivalent to "delete=f06,f04,log";
      "delete=all" deletes all standard output files;  "delete=jid" is ignored
      if not in server mode.  The default is "delete=no".
    delivery={pathname,"MSCDEF"}
      Alternate delivery database prefix or "MSCDEF".  This keyword overrides
      all MSC-supplied solution sequences.  The file type of the file must be
      ".MASTERA".  If a directory is not specified and the file does not exist
      in the current directory, the default delivery database directory is
      assumed.  The default is "delivery=MSCDEF".
    diag=flag[,flag,...]
      Set MSC.Nastran diagnostic flags.  The values may be separated with
      spaces or commas.  These diagnostics are set in addition to any
      diagnostics set via the Executive Control "DIAG" statement in the input
      data file.
    diaga=number
      Set MSC.Nastran diagnostic flags 1-32.  The value specified over-rides
      any previous "diag=n" values where n is in the range 1 to 32.  These
      diagnostics are set in addition to any diagnostics set via the Executive
      Control "DIAG" statement in the input data file. See the "MSC.Nastran
      Quick Reference Guide", Section 1, The NASTRAN Statement.
      This value may also be set with the "sys25" keyword.
    diagb=number
      Set MSC.Nastran diagnostic flags 33-64.  The value specified over-rides
      any previous "diag=n" values where n is in the range 33 to 64.  These
      diagnostics are set in addition to any diagnostics set via the Executive
      Control "DIAG" statement in the input data file. See the "MSC.Nastran
      Quick Reference Guide", Section 1, The NASTRAN Statement.
      This value may also be set with the "sys61" keyword.
    display=display_name
      UNIX systems only.
      Specify a display for XMONAST.
      This value may also be set with the DISPLAY environment variable.  The
      environment variable overrides the RC files; the command line overrides
      the environment variable.
    executable=pathname
      Alternate solver executable.  This keyword overrides all architecture
      and processor selection logic.  If a directory is not specified and the
      file does not exist in the current directory, the default executable
      directory is assumed.
    expjid={"yes","no","auto",pathname}
      Expand input file.  If "node=" specified and "expjid=auto" specified,
      input file will be expanded only if it not visible from remote node.  If
      "node=" not specifed and "expjid=auto" specified, "expjid=no" will be
      assumed.  If "dmparallel" >= 1, any "expjid" specification will be
      ignored.  If "expjid=pathname" is not specified and if input file is
      expanded it will be expanded to 'output_directory'/'jid-basename'.exp.
      If input file is expanded and "node=" is not expanded, processing will
      be terminated after the input file has been expanded.  This keyword is
      completely ignored in "server" mode, i.e., when "-annn" is specified and
      "nnn" is not 0.  Default is "expjid=auto".
    extdefault=logname(newext),...
      Specify alternate extension (file type) for specified logical name(s).
      May be repeated as often as necessary.
    f04=number
      Specifies FORTRAN unit number for Execution Summary Table.  The default
      is 4.  See the "MSC.Nastran Quick Reference Guide", Section 1, The
      NASTRAN Statement.
      This value may also be set with the "sys86" keyword.
    f06=number
      Specifies FORTRAN unit number for standard output file.  The default is
      6.  See the "MSC.Nastran Quick Reference Guide", Section 1, The NASTRAN
      Statement.
      This value may also be set with the "sys2" keyword.
    gmconn=pathname
      Geometric evaluator connection file.  There is no default value.
    ishellext=type=processor[,type=processor,...]
      Define processor associations.  This list defines the processor used by
      MSC.Nastran to execute an ISHELL program based on its file type.  The
      default is operating system dependent.
      This value may also be set with the MSC_ISHELLEXT environment variable.
      The environment variable overrides the RC files; the command line
      overrides the environment variable.
    ishellpath=path
      Additional path for ISHELL module.  MSC.Nastran will attempt to locate
      ISHELL module programs on this path before searching the standard PATH.
      The path value may include environment variable references, e.g.,
      "jidpath=$HOME/mytpl:$HOME".  The default is the directory containing
      the input data file.
      This value may also be set with the MSC_ISHELLPATH environment variable.
      The environment variable overrides the RC files; the command line
      overrides the environment variable.
    jid=pathname
      Input data file.  An input file must be defined on the command line.
      There is no default value.
    jidpath=path
      Additional path for input data file searching.  MSC.Nastran will attempt
      to locate the input data file on this path if the input data file name
      does not have a directory component and cannot be found in the current
      directory.  The path value may include environment variable references,
      e.g., "jidpath=$HOME/mytpl:$HOME".  There is no default path.
      This value may also be set with the MSC_JIDPATH environment variable.
      The environment variable overrides the RC files; the command line
      overrides the environment variable.
    jidtype=file_type
      Default file type for the input data file.  This keyword may be
      specified on the command line, or in the system RC files, the HOME RC
      file, or an RC file explicitly named with the "rcf" keyword.  The
      default is "jidtype=.dat"; if not defined by the user, "jidtype" shall
      be set to the file type of the actual input  data file.
    locbulk=number
      Specifies that special Bulk Data processing is in effect.  The default
      is 0.  See the "MSC.Nastran Quick Reference Guide", Section 1, The
      NASTRAN Statement.
      This value may also be set with the "sys143" keyword.
    lsymbol=name=value
      Assign a value to a "local" symbolic name.  The syntax and usage is
      identical to the "symbol" keyword syntax except that symbolic names
      defined using this keyword will not be passed to remote hosts, i.e., to
      hosts specified by the "node=" keyword.  When "node=" is not specified,
      symbolic names defined using this keyword will over-ride symbolic names
      specified using the "symbol" keyword.
    maxlines=number
      Specifies maximum number of output lines.  See the "MSC.Nastran Quick
      Reference Guide", Section 1, The NASTRAN Statement. The default is
      999999999.
    memory={memory_size,"estimate"}
      Size, in words, of open core.  If "memory=estimate" is specified, the
      memory size will be determined by ESTIMATE.  Otherwise, a positive
      non-zero value must be specified.  The default is "memory=estimate".
      Valid memory specifications are nB, nW, nKB, nKW, nK, nMB, nMW, nM, nGB,
      nGW, nG, n*physical, and n*virtual.
    memorydefault=memory_size
      Default size, in words, of open core.  This value is used if and only if
      "memory=estimate" was specified and the ESTIMATE utility failed.  The
      default is "memorydefault=8MW".
      Valid memory specifications are nB, nW, nKB, nKW, nK, nMB, nMW, nM, nGB,
      nGW, nG, n*physical, and n*virtual.
    memorymaximum=memory_size
      Maximum size, in words, of open core.  The default is machine dependent;
      on this platform it is "memorymax=0.8*physical" (see Appendix C in the
      "MSC.Nastran Installation and Operations Guide").
      Valid memory specifications are nB, nW, nKB, nKW, nK, nMB, nMW, nM, nGB,
      nGW, nG, n*physical, and n*virtual.
      Note: If you refer to physical or virtual memory, the physical or
      virtual memory must be known, otherwise this limit will be ignored.  See
      also the "s.pmem" and "s.vmem" keywords.
    metime=number
      Minimum time for execution summary table message.  See the "MSC.Nastran
      Quick Reference Guide", Section 1, The NASTRAN Statement.
      This value may also be set with the "sys20" keyword.
    mnfwriteoptions=string
      MSC.ADAMS MNF file processing options.  There is no default value.
      This value may also be set with the MDI_MNFWRITE_OPTIONS environment
      variable.  The environment variable overrides the RC files; the command
      line overrides the environment variable.
    ncmd=command_string
      Command to notify user that the job has completed.  The default
      notification will use the Korn shell print command if "batch=no" is in
      effect or write(1) otherwise.
    news={"yes","no","auto"}
      Display site's news and release notes in the F06 file.  The "news=auto"
      keyword will only print the news file if it has changed since the last
      time it was printed.  The default is "news=yes".
    nice={"yes","no",number}
      Request that "nice" mode, i.e., lower priority, be used when analysis is
      run. The default is "nice=yes" in background mode ("batch=yes") and
      "nice=no" in foreground mode ("batch=no").
    nlines=number
      Specifies number of lines printed per page of output.  See the

      NQS/NQE batch job, the default is "notify=no".
    old={"yes","no"}
      Save existing output files.  If "old=yes", the existing output files are
      renamed with a version number; if "old=no", the existing output file are
      deleted.  The default is "old=yes".
    oldtypes=file_types
      A comma-separated list of user file types, excluding the ".", that will
      be versioned if "old=yes" is specified, or deleted if "old=no" is
      specified.  These file types are in addition to the standard file types,
      e.g., f04, f06, log, etc.  File types that can be modified using
      "extdefault" must be specified in the form "logname(filetype)". There is
      no default value.
      This value may also be set with the MSC_OLDTYPES environment variable.
      The environment variable overrides the RC files; the command line
      overrides the environment variable.
    out=pathname_prefix
      Alternate output file prefix.  If the prefix is a directory,
      'jid-basename' is appended.  The default is "out=./'jid-basename'".
    post=command_string
      User command(s) run at job completion.  Every occurence of "post" in an
      RC file or on the command line will be executed.  Setting a null value,
      i.e., "post=", will erase the currently saved commands.  There is no
      default value.
    pre=command_string
      User command(s) run at job start.  Every occurence of "pre" in an RC
      file or on the command line will be executed.  Setting a null value,
      i.e., "pre=", will erase the currently saved commands.  There is no
      default value.
    processor=file_type
      File type of alternate executable.  This keyword overrides the default
      processor subtype selection logic.  There is no default value.
    punch=number
      Specifies FORTRAN unit number for PUNCH file.  The default is 7.  See
      the "MSC.Nastran Quick Reference Guide", Section 1, The NASTRAN
      Statement.
      This value may also be set with the "sys64" keyword.
    radlst=number

      Guide", Section 1, The NASTRAN Statement.
      This value may also be set with the "sys88" keyword.
    rcf=pathname
      File containing additional keywords.  Replaces the local RC file.  This
      keyword may only be specified on the command line.  There is no default
      value.
    rdelivery={pathname,"MSCDEF"}
      Remote Node alternate delivery database prefix or "MSCDEF".  This
      keyword overrides all MSC-supplied solution sequences.  The file type of
      the file must be ".MASTERA".  If a directory is not specified, the
      default delivery database directory is assumed.  The default is
      "delivery=MSCDEF".  This keyword is ignored unless "node=" is specified.
    rexecutable=pathname
      Remote Node alternate solver executable.  This keyword overrides all
      architecture and processor selection logic.  If a directory is not
      specified, the default executable directory is assumed.  This keyword is
      ignored unless "node=" is specified.
    rgmconn=pathname
      Remote Node Geometric evaluator connection file.  There is no default
      value.  This keyword is ignored unless "node=" is specified.
    scr300=number
      Requests creation of SCR300 partition on SCRATCH DBset.  See the
      "MSC.Nastran Quick Reference Guide", Section 1, The NASTRAN Statement.

      This value may also be set with the "sys150" keyword.
    symbol=name=value
      Assign a value to a symbolic name; the name may be used in a filename
      reference on the command line, in an RC file, or in the data file.  All
      environment variables can be used as symbols.  A symbol definition can
      include an environment variable reference, e.g.,
      "symbol=mysymbol=$HOME/mydir".  The environment variable overrides the
      RC files; the command line overrides the environment variable.  If
      "node=" is specified, the specified symbol value must be valid on the
      remote node.  Use the "lsymbol" keyword to set "local" symbol values to
      be used when "node=" is specified.
    system=number
      Assign a value to a system cell.  The keyword can be specified as either
      "SYSn=value" or "SYSTEM(n)=value" where n is the system cell being set.
      For example, either "SYS107=2" or "SYSTEM(107)=2" will set SYSTEM cell
      107 to 2.  If the latter form is used on the command line, it must be
      quoted to prevent interaction with the shell.  There is no default value.
    t3skew=number

    trans={"yes","no","auto"}
      Indicates the XDB file is to be converted to neutral format using the
      TRANS utility if the "node" keyword is not specified.  Indicates the XDB
      file is to be copied from the remote node if the "node" keyword is
      specified.  If "trans=yes", use TRANS/RECEIVE to copy the XDB file from
      the remote node.  If "trans=auto", use TRANS/RECEIVE only if needed;
      otherwise use a binary copy.  If "trans=no", do not copy the XDB file
      from the remote node.  The default is "trans=auto".
    version=version_number
      Selects the version to be run, e.g., "version=2005.5".  This keyword may
      only be specified on the command line or in the command initialization
      file.  The default is the latest installed version.
    xmonitor={"yes","no","kill"}
      UNIX systems only.
      Run XMONAST to monitor the job's progress.  "xmonitor=kill" will
      terminate XMONAST at job completion.  The default is "xmonitor=no".

 Database keywords:
    attdel=number
      Controls automatic assignment of the delivery database.  The default is
      0 (enable).  See the "MSC.Nastran Quick Reference Guide", Section 1, The
      NASTRAN Statement.
      This value may also be set with the "sys124" keyword.
    autoasgn=number
      Controls auto-assigning of DBSets.  The default is 7 (auto-assign all).

    bpool=number
      Number of GINO blocks allocated to buffer pool (in open core).  The
      default is machine dependent (see Appendix C in the "MSC.Nastran
      Installation and Operations Guide").  This keyword is a synonym for the
      "buffpool" keyword.
      This value may also be set with the "buffpool" or "sys114" keyword.
    buffpool=number
      Number of GINO blocks allocated to buffer pool (in open core).  The
      default is machine dependent (see Appendix C in the "MSC.Nastran
      Installation and Operations Guide").
      This value may also be set with the "sys114" keyword.
    buffsize={number,"estimate"}
      Size, in words, of a GINO buffer.  If "buffsize=estimate" is specified,
      the BUFFSIZE will be determined by ESTIMATE.  Otherwise, the value must
      be one plus a multiple of the disk block size in words.  The default is
      machine dependent (see Appendix C in the "MSC.Nastran Installation and
      Operations Guide").
      This value may also be set with the "sys1" keyword.
    cpyinput={"0","1"}
      "Copy Input File" flag, where 0 means "no", 1 means "yes".  The default
      is 0 (no copy). See the "MSC.Nastran Quick Reference Guide", Section 1,
      The NASTRAN Statement.
      This value may also be set with the "sys305" keyword.
    dbs=pathname_prefix
      Alternate user database prefix.  Overrides "scratch=yes".  If the prefix
      is a directory, 'jid-basename' is appended.
      The default is "dbs=./'jid-basename'".
      When used for remote processing (see "node"), this pathname must be
      valid on the remote system unless "rdbs=" is specified.  If "dmparallel"
      >= 1, unique database directories may be set for each task using the ":"
      character to separate entries; the names will be paired with the tasks
      in round-robin order.
    dbverchk={"0","1"}
      Specifies whether or not database version checking is to be skipped.
      The default is 0 (no skip). See the "MSC.Nastran Quick Reference Guide",
      Section 1, The NASTRAN Statement.
      This value may also be set with the "sys148" keyword.
    hpio_param=string
      SUPER-UX and IA64 Azusa systems only.
      HPIO specification.  There is no default value.
      This value may also be set with the HPIO_PARAM environment variable.
      The environment variable overrides the RC files; the command line
      overrides the environment variable.
    rdbs=pathname_prefix
      Remote Node alternate user database prefix.  Overrides "scratch=yes" and
      "dbs=".  If the prefix is a directory, 'jid-basename' is appended.
      The default on the remote node is "dbs=./'jid-basename'".
      This keyword is ignored unless "node=" is specified.
    rsdirectory=pathname
      Remote Node directory for scratch files.  This is the default directory
      for user database files if "scratch=yes".  The default is taken from the
      TMPDIR environment variable if it is defined, otherwise it is machine
      dependent (see Appendix C in the "MSC.Nastran Installation and
      Operations Guide").  This keyword is ignored unless "node=" is specified.
    scratch={"yes","no","mini","post"}
      Delete database files at job completion.  "Scratch=yes" is equivalent to
      the FMS statement "INIT MASTER(S)".  Setting the "dbs" keyword in an RC
      file or on the command line overrides "scratch=yes".  "Scratch=mini"
      selects the "mini database" option, this reduces the size of the
      database if it will only be used for data recovery restarts.  The
      default is "scratch=no".
    sdball={db_size,"estimate"}
      Default size, in GINO blocks, of the DBALL DBset.  This number may also
      be specified in words or bytes if followed by a unit modifier.  If
      "sdball=estimate" is specified, the DBset size will be determined by
      ESTIMATE.  The FMS INIT statement overrides this keyword.  The default
      is machine dependent (see Appendix C in the "MSC.Nastran Installation
      and Operations Guide").
      Valid unit modifiers are B, W, KB, KW, K, MB, MW, M, GB, GW, G, TB, TW,
      T.
    sdirectory=pathname
      Directory for scratch files.  This is the default directory for user
      database files if "scratch=yes".  The default is taken from the TMPDIR
      environment variable if it is defined, otherwise it is machine dependent
      (see Appendix C in the "MSC.Nastran Installation and Operations Guide").
      When used for remote processing (see "node"), this pathname must be
      valid on the remote system unless "rsdirectory=" is specified.
      If "dmparallel" >= 1, unique scratch directories may set for each task
      using the ":" character to separate entries; the names will be paired
      with the tasks in round-robin order.
    smaster=db_size
      Default size, in GINO blocks, of the MASTER DBset.  This number may also
      be specified in words or bytes if followed by a unit modifier.  The FMS
      INIT statement overrides this keyword.  The default is machine dependent
      (see Appendix C in the "MSC.Nastran Installation and Operations Guide").
      Valid unit modifiers are B, W, KB, KW, K, MB, MW, M, GB, GW, G, TB, TW,
      T.
    smemory=number, memory_size
      Number of GINO blocks of SCRATCH & SCR300 files kept in open core.  This
      number may also be specified in words or bytes if followed by a unit
      modifier.  The default is 100.  The FMS INIT statement overrides this
      keyword.
      Valid unit modifiers are B, W, KB, KW, K, MB, MW, M, GB, GW, G, TB, TW,
      T.
    sscratch={db_size,"estimate"}
      Default size, in GINO blocks, of the SCRATCH & SCR300 DBsets.  This
      number may also be specified in words or bytes if followed by a unit
      modifier.  If "sscr=estimate" is specified, the DBset size will be
      determined by ESTIMATE.  The FMS INIT statement overrides this keyword.
      The default is machine dependent (see Appendix C in the "MSC.Nastran
      Installation and Operations Guide").
      Valid unit modifiers are B, W, KB, KW, K, MB, MW, M, GB, GW, G, TB, TW,
      T.
    sysfield=string
      Specifies a default value for the SYS keyword on all FMS ASSIGN
      statements associated with DBsets.  The string specification is not case
      sensitive.  There is no default value.
