Re: Using *OMIT & *NOPASS

Rob,

When you define a command, you define the parameter interface for the
command processing program.  All the parameters you define will be passed to
your program.  If you define a 10A parameter with no default value and the
user does not enter anything for it, you receive a 10A field containing
blanks.
