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
