Not-equal, <>, is an inequality operator to test whether two values are unequal.

Description

<> evaluates the expressions on either side, and compares their values. If the values are unequal (i.e. not equal), it returns the Boolean value TRUE, otherwise it returns FALSE. It is usually used as the condition of an IF statement, but it is equally valid to assign the result to a variable.

It is not possible to daisy-chain (in)equality tests (for example IF bool% <> X = Y THEN ...), as the Group 5 operators do not associate. Please see = for more details.
