ISNOTNULL function  

Purpose

Determine if a string is not null (contains 1 or more characters).

Syntax

ResultVar& = ISNOTNULL(StrgExpr)

Remarks

The StrgExpr is examined to determine if it is null, or if it contains one or more characters.  The value true (-1) is returned if the StrgExpr contains characters, or false (0) if it is null (zero-length).

The complementary function is ISNULL.
