(Recursive) nested loops and IFs?

[chromos]

I had unhandled A/B type expressions, so I modified your previous code into...

PHP Code:

IF ΠLIST(EXECON("EXPR(&1)>=0 AND EXPR(&1)<=9 AND FP(EXPR(&1))==0",L5)) THEN 


... and it works.
In your new code...

PHP Code:

IF ΠLIST(EXPR(L5+">=0") AND EXPR(L5+"<=9") AND EXPR(FP(L5)+"==0")) THEN 


... it doesn't work. Your unmodified code works.
