Hi Trey
I just created a Wiki entry and gave credit to all contributors in this thread. I hope none find that too presumptuous.
The UDF I made adds traps for incorrect calls to IsArray.PRG.
http://fox.wikis.com/wc.dll?Wiki~IsArray~VFPI added a new category CategoryUDF, where we can find ready-to-use routines.
