What I am looking for is a method to test conditions in a field I have already read from the file (or screen).%LOOKUP works very well for this. SETLL isn't too bad, either, especially if the codes can change. If you start hardcoding lists of values in SQL statements, you're setting yourself up for a maintenance nightmare down the road.
Basically a shortcut method using SQL instead of multiple and/or conditions in an IF statement.
ie: Test field Order_Line_Code for values 'MS', M1',MO','LS' ....
In SQL, I can just list the values to test using the IN condition, but in RPG I would have to test each value separately.
I do not know if this can be done, but figured that if it could, than this list was the place to find out.
