Re: Managing multiple &FIELDS in a screen using CL

[Booth Martin <booth@xxxxxxxxxxxx>]

FWIW, consider using "MLTCHCFLD (Multiple-Choice Selection Field) 
keyword for display files"  (check boxes) for a screen with 60 choices. 
 Much easier to layout, and much easier to deal with.  Check boxes are 
entirely mousable.

Here's how they look:

or

Circles are radio buttons, squares are check boxes.

If you can, find a way to use RPG  -  much easier.

I want to use a DOFOR to check all of them and turn on a flag whenever I find one of these fields with some content in it.  I would like to do something like this:
