rpg style question

Hi,

Having to regularly determine the value of flags as 'Y' or 'N', then record it in a PF.

This means having to code

IF rules satisfied;
MyFlag = gYES;

ELSE;
MyFlag = gNO;
Endif;


Then, maybe in another module,etc

IF MyFlag <> gYES;
Don't do stuff;
ELSE;
Do stuff;
Endif

Comments?
What's the reasoning behind this method?

I'd <like> to be able to use an indicator :

MyFlag = ( rules satisfied);

Then,

IF MyFlag;
do stuff;
ELSE;
Don't Do stuff;
Endif


Thanks.
