RE: passing along *NoPass arguments

Hi Steve -
Hopefully a *NoPass parm variable has something like an associated attribute byte that contains the pass/nopass status of the variable.
Nope. *nopass means that nothing is passed. No pointer, no flags, nothing. The only way to tell if the parameter has been passed or not is by the parameter count.

The storage area where a pointer to the that parameter would be if it were passed could contain anything, including a valid pointer.

*omit without *nopass is the way to have a status because then something is always passed, either a valid pointer or a null pointer.
