# Ends with (=*) and does not end with (!=*)

## Overview

Use the symbol=*to notate the inequality 'ends with', or

!=*to notate the inequality 'does not end with'.

For example:

*ABC =* C AND ABC !=* A*

means:

*ABC ends with C and ABC does not end with A*

## Details

The expressions*a*and

*b*in the inequality

*a =* b*, or

*a !=* b*should be substituted by any of the following:

- a fixed text string, for example

*hypertension*

- a fixed numerical value, for example

*12.3*, also valid is

*12,3*

- a global variable, for example

*$hour$*

- any other variable or variable parameter, for example

*$Design.Constant 1.Value$*, or

*$LastName$*.

Variables are substituted by their current values at the time the inequality is processed. Spaces around the expressions are trimmed automatically.

The way the inequality is solved depends on the type of its expressions:

**Both expressions are numbers**

Because there is no numerical representation of 'ends with', the inequality is always handled as text.

**Both expressions are textual**

If a text string is to be compared to another text string, then comparison is case sensitive.

For example:

*Hello =* llo*evaluates to TRUE, because the first expression ends with the second.

*$var$ !=* morning*evaluates to TRUE in case the variable $var$ has been set to "Good day".

**One of both expressions is textual, the other is a number**

If one of both expressions is a text, then the other expression is also handled like text.
