Hi Mike; Thanks for the helpful response. I am glad that u were able to sort the initial problem out. I was originally drawn to respond by the fact that there was a segment address of 0000:, which i thought was illegal, but it has been several years since i have messed around with 80x86 asm. I am doing 8051's this summer, unfortunately. The one thing that i would point out is that it seems that even ls.exe is a little ambitious. I would try and go after a subcomponent of that first. Let's see, are u guys chasing int21? let me grab my dos and bios quick reference...int21/01 keyboard input with echo? int21/02 display output. These are calls that u could hack together to try out smaller chunks. ls.exe asks for keyboard, display and disk visits. if u were to take the gcc -s output of ls.c and use the subchunks to prove simpler chunks, u might have a more managable problem IMHO. but, hey, these are things i can try as soon as i get this 2.0.5 upgrade finished. mucho tnx for all the work u guys have put into it so far.... ******************************************************************************* John Utz spaz@u.washington.edu idiocy is the impulse function in the convolution of life
