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;
