1  –  Qualifiers

1.1    /FORM_NAME

  library_spec/FORM_NAME=(form_name,...)

  Output  descriptions  for  the  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 output.

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

1.2    /LOG

  /LOG
  /NOLOG (D)

  The  /LOG qualifier causes a log of all forms for which  descriptions
  are generated  to  be  output  to the device  SYS$OUTPUT.  The /NOLOG
  form which is the default disables logging.

1.3    /OUTPUT

  /OUTPUT=file_spec (D)
  /NOOUTPUT

  The  /OUTPUT  qualifier  allows  you to supply a name for the  output
  description file.  If the file specification  is  omitted  the output
  defaults to SYS$OUTPUT.  The /NOOUTPUT qualifier  causes output to be
  discarded.
