The  FMS/LIBRARY/REPLACE  command  places  the  specified  form in an
  output  form  library.  Input  forms replace forms that have the same
  name  in the form library. If any of the input files contain the same
  name,   the  last  form  specified  is  inserted  in the library. The
  default  input  file  type is FRM and the default output file type is
  FLB.

1  –  Qualifiers

1.1    /FORM_NAME

  library_spec/FORM_NAME=(form_name,...)

  Extract  from  the  input  library  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  copied to
  the output library - especially useful if an entire  existing library
  is input.  The /NOLOG qualifier disables logging.
