Ah, but if you're using WDSC, then the outline view shows you which params are 
VALUE or CONST.  No need to page the source itself up.

My personal mantra...if you're trying to use SEU to do true RPG IV 
programming...you're wrong.
Two main reasons:
1) The usefulness of the outline view
2) How easy "Auto-Complete" aka "Code Assist" makes it to use longer names.

Correct.

No problem.
