Hi All I've just picked up a copy of MASM 6.1 and would like to teach myself assmebly programming. The books that came with MASM are good, but I feel I'm getting lost in all the snippets of code, (a lot of the example code are procedures or parts of a program). You know of a tutorial I can d/l or view on the web, let me know. Thanks ...

The one in the bootsector is new, came with DOS 4, I think. I'm not sure what good it is, actually. ;) Even DOS 6.22 seems to look in the root directory for the volume ID. --Scott. --- timEd 1.01 * Origin: Wizard's PC Services, BBS=254-554-2146, Pager=903-3097 (1:395/11)
