Re: System 36 internal display file

Hi Mark,

As long as there are comments identifying the output specs that go with
which input specs, I agree with you.  However, you _could_ define the record
ID as a protected, non-display I/O field. For debugging, remove the
non-display attribute to be sure you're getting what you think you are.
Although I suppose if you want to conserve screen real-estate a hidden field
is better.

Actually, I like to put the name of the format visibly on the screen
somewhere so that when users ask for a modification, they have a reference
name. At least with RPG III and RPG IV we don't need to worry so much about
the input specs!
