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.
