NOT(), NOTS() |
![]() ![]() ![]() |
The NOT() function returns the logical inverse of its argument. The NOTS() function is similar to NOT() but operates on successive elements of a dynamic array, returning a similarly structured dynamic array of results.
Format
NOT(expr)
where
The NOT() function returns the logical inverse of expr. If expr is zero (or a null string which equates to zero), the NOT() function returns true (1). If expr is non-zero, the NOT() function returns false (0).
Example
IF NOT(NUM(S)) THEN GOTO ERROR
This statement causes the program to jump to label ERROR if S is not numeric.
