contains

Syntax

stringExpression1 contains stringExpression2 

Description

Operator; compares two strings and determines whether stringExpression1 contains stringExpression2 (TRUE) or not (FALSE).

The contains comparison operator has a precedence level of 1.

The contains comparison operator is useful for checking whether the user types a specific character or string of characters. You can also use the contains operator to search one or more fields for specific strings of characters.

Note: The string comparison is not case sensitive, but it is sensitive to diacritical marks; "a" and "A" are treated the same, but "A" and "Ä" are not.

Example

This example determines whether a character passed to it is a digit:

on isNumber aLetter
	digits = "1234567890"
	if digits contains aLetter then
		return TRUE
	else
		return FALSE
	end if
end
