rel_exp - IS REQUESTED

Obsolete Syntax

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

Effect

This predicate expression checks whether an output parameter para of a procedure is being requested. The expression is true if at the call an actual parameter was assigned to the formal parameter.

This expression is possible only in function modules and methods. para expects 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.

Notes

• The predicate IS REQUESTED should no longer be used. The predicate expression IS SUPPLIED can be used instead, which includes all functions of IS REQUESTED.

• In update function modules, checks on table parameters using IS REQUESTED produce a syntax check warning. This is because an actual parameter is always assigned to the table parameter in this case.
