... para IS [NOT] REQUESTED ...

This logical expression checks whether an output parameter para 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 para, 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.

Note

The predicateIS REQUESTED must not be used any more. The predicate IS SUPPLIED can be used instead, it covers the function of IS REQUESTED.
