Kurt, nice because the code is more contained, but,
to your point, it's like carving soap with a razor
and arrays are safer.
And, thanks to Paul Tuohy and his
"Those Weird and Wonderful Arrays" article, I use
them to provide flexible sorting for our warehouse
pallet staging function, and use a basing pointer
to switch between door arrays by delivery truck type
for door assignment.
Thank you Paul, thank you IBM RPGLE team!
But, I want my IN operator.
Monday would be nice. (please?)

Wait, how is that nice?
Why would you use that method over using an array? As Eric even said, there are inherent risks to searching a string for values. I don't see the benefit.
I know it's Friday, but it's Friday 2013. (Not that arrays are a new concept.)

Eric, nice, avoids the array, challenges my brain...

I have sometimes used %scan() to provide some similar functionality. There are some risks associated with this, so take care to not hurt yourself...
myCustomerExemptTypes = '("NONEXEMPT", "RETAILEXEMPT", "FULLYEXEMPT")'; chain myCust Customer; if %scan( '"'+%trim(CustExTyp)+'"' : myCustomerExemptTypes ) > 0;
// non-zero means FOUND (is Valid)
Endif;
It's important to use delimiters to define values, and to enclose the scan string in like fashion. Parentheses for the list string are not necessary, but I like to use them (or [], {}) to so some sort of "dataset" relationship.
Hth,

Ever wonder why there is no If IN (not to be confused with *IN) ?
If MyCharVar In ('A','B','C');
MyFace = ': )';
Else;
MyFace = ':(';
Endif;
