myString='OP101,TH310,XB171'
myDept='TH,BR'
Is there a function that returns .T. if either "TH" or "BR" is in myString?

?INLIST(myString,'TH,BR') returns .F.
?INLIST(myString,'TH','BR') returns .F.
?'TH,BR' $ myString returns .F.

myString is a string, listing (dept code + product code)s, separated by commas. The first 2 chars is Dept code, followed by the product code (example: OP is the dept code, 101 is the product code, etc.)
myDept is a string, listing department codes (separated by commas).
What I'm looking for is a function that will return .T. if any one of the department codes listed in myDept is in myString.

Is there such a thing?
Thanks all!
