Question

How do OPTVALs work?

Answer

  OPTVAL allows you to retrieve the value of a user-defined option from the
  script command.

  Only CMS allows user-defined options.  The coding could look like:

      .gs optval OS
      .if &E'&OS eq 0 .mg /I/No Operating System ...VM is Default/
      .th .se OS = VM
      .th .go vminfo
      .if &OS eq VM .go vminfo
      .if &OS eq MVS .go mvsinfo
      .if &OS eq DOS1 .go dos1info
      .if &OS eq DOS2 .go dos2info

  Your SCRIPT command would need the following user-defined options:

      @OS(VM) or @OS(MVS) or @OS(DOS1) or @OS(DOS2)
