issetv(var vA)
Remarks
Test commands are only valid in an if statement.
The issetv command returns TRUE if the flag whose number matches the value of vA is set, FALSE if it is not. For example, if v50 equals 40, then issetv(v50) returns TRUE if flag f40 is set.
This statement can be combined with the NOT operator to create an ‘indirect flag not set’ test.
