(http://www.quadibloc.com/comp/cp0303.htm). I vivdly recall having to compile (using #XEKA/B) then consolidate (#XPCK) my COBOL programs (once they'd been keyed from coding sheets onto 80-character cards and loaded of course!), then pore through the consolidation listing to identify the particularly inefficient code (most of it in my case), then make it more efficient to squeeze it into the allotted 32K. Before the happy days of overlaying techniques, of course. How I miss PIC S9(6) COMP SYNC RIGHT ! (I miss the George 3 editor more, but that's an even sadder story) Regards Glyn > and the memory module alone was about 5 feet high by about 5 feet wide > and about 3 feet deep.
