expression (!)?= expression
A logical operator, used to compare two numeric expressions. Can be used either as = (is equal) or as != (isnt equal). Though is equal and isnt equal are valid, it has become more common to use the symbols = and !=, respectively. is equal can be used with string expressions as well as numeric expressions.
do when a = b ... done
do when a != b ... done
Note that = and != can also be used to compare two test expressions for equality or inequality.
With OmniMark V3, you can use the = operator to perform multi-part switch comparisons.
