Boy, I wonder if it weren't possible to write and IN() function in RPG.
Maybe pass in the variable you are testing and have an array of the
values to test, use some way to vary the count, and return an indicator.
Woohoo!!!

I think that the best you can do is a function working for one type, and
only allowing up to some fixed maximum number of values to test.

Meanwhile, and expression like "0 < %lookup( ... )" can sometimes
approximate what you want. Of course, sometimes you would rather have
the test values manifest in-line.

Cheers,
Terry.
