!=
Syntax object != object
!= object object
object <> object
<> object object
.NE object object

 
Explanation The Not Equal operator compares two objects. If they are not equal, the output is TRUE; otherwise it is FALSE. The Not Equal operator may be expressed as !=, <>, or .NE.

The <> and != forms may be used either as a prefix or as an infix operator, although it must be surrounded by parentheses if its output is used in infix mode (not simply at the command line).

Example 4 != 5
Result: TRUE
<> 4 5
Result: TRUE
.NE 5 5
Result: FALSE
