Re: Preventing a divide by zero error

This sounds like an easy an easy thing to check for, but here's what is
going on:

I'm studying (on my own) RPG IV using Stanley Myers' book, "RPG IV
Programming on the AS/400". I'm doing the programming assignments at
the end of Chapter 5, and assignment 5-2 wants "Include the control that
prevents a divide-by-zero error". As far as I can tell, this hasn't
been discussed in the book yet; so I don't want to jump ahead with a
solution that isn't what they are really looking for.

This is what the line in question could be something like:

C EVAL GRPFT = NETPRICE / GROSSPRFT

Is there some EVAL option I'm missing for this? Setting indicators is
discussed, but for the life of me I don't see anything related to divide
by zero.

I did some searching, but I found what I would logically do to check for
a zero in the variable before doing the math. That hasn't been covered
in this book yet, so I'm guessing there is something else to it.
