This technique may be used if you are using a rules based system that is
modified without coding. 

For example: 

Having seen this in several pricing systems, it is useful when at the
time the order was placed, the order passed the rules then in force.  If
at a later date when the order is finally processed you do not have to
try to "back-date" the rules processing.  There are times when some
rules are at original entry versus at point of use.

Subject: 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.
