Don't you mean BASIC or DEBUG? Run debug, then type "O 378 FF" (no

Alan: I am NOT a "programmer" (though I DO that primitively, with
challenge!), but I THINK you are confusing DOS with Assembly ("machine-") code. yes, in
ASM-86, invoked by "DEBUG", causing the machine to LEAVE DOS and enter
machine-code, you would write OUT 378 FF to make all-8 bits of the printer-port HI.
But in DOS, too, you can write OUT 378,FF as well. OR GWBASIC (and I ASSUME
QBASIC?) OUT 888,255, or OUT &H378,&HFF to do same. I never used QBASIC, but
at least GWBASIC requires the "&H..." before a number in HEX, but NO prefix
for a base-10 ("decimal") number.
