Yes, its very easy to do.... First you intercept the normal BIOS/GEMDOS/XBIOS vetctor, then you changes the returnadress on the stack and do what you want, and jump to the call, when return you can do somthing else (in user-mode) and then you can jump to the normal program than called the GEMDOS. Have a small program that fixes redirection of I/O. (> file.ext) for all programs.... Will post it some day - its very handy for BBS-systems (LHARC does not have redirect built in) Lars-Erik / ABK-BBS +47 2132659 / ____ ______ Osterud / larserio@ifi.uio.no / /___ / ____________/ _______________________/ ____/ /
