Hi all. This is weird. I was typing up this message, and before I completed it, I tried something out which fixed the problem. But I thought I'd share it with the list anyway, as I don't understand it. Here's my original question: I have a simple RPG procedure which returns a one-character value (*on or *off, but that doesn't seem to be relevant, as I get the same problem if I code a literal '1' or '0'). I'm calling it from a CL procedure, using CALLPRC with the RTNVAL parameter. The field for RTNVAL is defined as *CHAR 1. I get MCH3601, pointer not set for location referenced, on the RETURN opcode. Neither debug nor a dump tells me anything. We are on V4R3. Anybody got any ideas? *** End of original question *** And then I prompted CALLPRC and hit help on RTNVAL; it mentioned the return value being 'aligned on a sixteen-byte boundary'. So on an impulse I redefined my return value field as *char 16. And it worked. I've come across this 'aligned on a sixteen-byte boundary' expression before, and never understood it; I eventually had concluded that it was a fancy way of saying pointers are sixteen bytes long; but I see that there's more to it than that. Can anybody explain what's going on here?
