The  FMS/VECTOR  command  generates  an  output  file  that  contains
  references  to  all user action routines in the specified form files.
  The  output file is in object format for linking with the application
  program  and Form Driver. The default input file type is FLB, and the
  default output file type is OBJ.

  Example:  FMS/VECTOR THISLIB

      The  input  file  is  THISLIB.FLB and THISLIB.OBJ is the output
      file. The output file  contains  data structures to provide the
      Form Driver with information to access the user action routines
      referenced in the library.

1  –  Qualifiers

1.1    /FORM_NAME

  library_spec/FORM_NAME=(form_name,...)

  Output  vector  information  for  those  forms  specified  after  the
  /FORM_NAME qualifier.  The qualifier applies only to the  immediately
  preceding form library.  If the /FORM_NAME qualifier  is omitted, the
  entire library is used.

  To name more than one form, enclose the list in parentheses.

1.2    /LOG

  /LOG
  /NOLOG (D)

  Produces  a  log  on the device SYS$OUTPUT showing the forms  used to
  create the output. The /NOLOG qualifier disables logging.

1.3    /OUTPUT

  /OUTPUT=file_spec (D)
  /NOOUTPUT

  The  /OUTPUT  qualifier  allows you to specify a name for the  output
  form file.   If the file specification is omitted  the output file is
  the  name of the first  input  file  with   the  file  type OBJ.  The
  /NOOUTPUT qualifier causes output to  be discarded.
