I have the following.

Dcl-s x_yes char(01);

How do I get x_yes set to 'Y' and x_no set to 'N';


I don't think anyone answered this part of your question yet. Use INZ.

Dcl-s x_yes char(01) inz('Y');
Dcl-s x_no char(01) inz('N');

(But I agree with others that using named constants would be best for things like these that should always have the same value.)

*shudder* I'm having a nasty flashback to some code I worked on long ago and far away that had global variables named N0 N1 N2 N3 N4 ... N100 and X1 X2 X3 ... X100, used throughout the code instead of numeric literals 0 1 2 etc, for who knows what reason. A coding error had set one of them (N1 if I recall correctly) to a new value which caused a bug that took me way too long to find. Lesson somewhat learned: Never assume that a variable contains what its name suggests.
