>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 evaluates the contents of the string. If the contents cannot be evaluated as a valid FoxPro expression, TYPE() returns "U" (undefined expression).

Jim,

What would you recive if you do place quotations, e.g.
?type("test(123)")? You would receive "U" if function test exists and U if it doesn't exist. If you would use vartype(test(123)) you would receive a type of value of the result of test function if it exists and an error, if it doesn't.

That's all, I'm saying.
