The INCREMENT-VARIABLE directive increments the value of the variable that is local to the input record being processed.
increment-variable <variable> <value> <expression>
The <variable>
is incremented by the <value>
when the <expression>
evaluates to
true.
This directive is applied only within the scope of the record being processed. The transient state is reset, once the system starts processing of the new record.
Internally, this directive increments a long
value.
