I'm going to re-engineer our ACS routines. They are a mess. But I'm curious about the "best" way. I've narrowed it down to two techniques. The simpliest, to me, is to just use a series of IF statements where the THEN portion ends with an EXIT to terminate the ACS routine. The more complicated, but perhaps more efficient, way is to use nested SWITCH and IF statements. I like the straight IF simply because I think it will be easier to understand. And I don't mean nested IFs. I mean something like:
IF cond1 AND cond2 AND cond3 THEN DO ... EXIT END IF cond1 AND cond2 THEN DO ... EXIT END IF cond1 THEN DO ... EXIT END instead of: IF cond1 THEN DO IF cond2 THEN DO IF cond3 THEN DO ... END ELSE DO ... END /* OF ELSE */ END /* OF IF cond2 */ ELSE DO /* OF IF cond1 */ ... END /* OF IF cond 1 */ Of course my "series of simple IFs" philosophy will result in more code being written and executed. I just have a "gut feel" that it will be easier to understand and maintain. I may relent a bit if I need to do a simple set of IFs within a DO. Perhaps it would be "no nested DO groups". Eg: IF cond1 AND cond2 THEN DO ... IF cond3 THEN SET .. IF cond4 THEN SET ... IF cond5 THEN SET ... IF cond6 THEN SET ... EXIT END I really want it to be simple and easy to understand and maintain. Not like my Perl and APL code! <grin> John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
