Re: CL pgm and pointer variables

Hi Scott -


If I recall correctly, pointers in OS/400 have special tag bits in memory
which are only set if they're manipulated using the MI or W-Code
operations designed for working with pointers.

Yes, but ...


If the CL program defines it as a character variable, those bits would not
be set correctly, and the system would refuse to treat it as a pointer.

The procedure that loaded the field would set the bits properly.  That's
why I said that as long the CL program does not manipulate the field, but
only just has it in the CALLPRC to the other procedures, it should work.
