Hi Jim,

I'm not so sure about this. For the sake of all concerned. Here's the description from the documentation:
cExpression

Specifies the expression to be evaluated, which can be a variable, field, memo field, or any other expression. The expression must be passed as a character string; place quotation marks around the names of memory variables, fields, and so on. If you do not place quotation marks around the expression, the TYPE( ) function returns "U" (undefined expression).

First the cExpression indicates a character expression not a variable or or type. Next the sentence that I've placed in bold type seems to contradict what you just said. Or do I need remedial reading< g >?
