... p IS [NOT] REQUESTED ...
The logical expression checks whether an output parameter p of a procedure is requested. The expression is true if at the call an actual parameter was assigned to the formal parameter.
This logical expression is possible only in function modules and methods. For p, you can specify only output parameters and optional input/output parameters.
With addition NOT, the expression is true if at the call no actual parameter was assigned to the formal parameter.
As of release 4.6, the functionality of the logical expression IS REQUESTED is covered by the logical expression with
IS SUPPLIED and should no longer be used.
