Description
The TYPE() function returns a letter code which represents the data type of the expression in <expC>. The return value of the letter code is a character string from the table below.

If <expC> contains a syntax error, or an undeclared variable, then TYPE() returns 'U'. TYPE() will also return a 'U' for an undefined variable if SET CLIPPER is ON. TYPE() is primarily used to check for the existence of a variable, or the syntax of an expression.
Example
i = 10 ? type("i") N
