stringP()

Syntax

stringP(expression)

Description

Function; determines whether an expression is a string (TRUE) or not (FALSE).

The P in stringP stands for predicate.

Example

put stringP("3")

The result is 1, which is the numeric equivalent of TRUE.

Example

This statement checks whether the floating-point number 3.0 is a string:

put stringP(3.0)

Because 3.0 is a floating-point number and not a string, the result is 0, which is the numeric equivalent of FALSE.
