Re: [CAD_CAM_EDM_DRO] Assembly Language

Here's how to do it in debug. <enter> means press the enter key.

debug <enter>
a<enter>
mov ax,5f00<enter>
int 10<enter>
int 3<enter>
<enter>
rcx<enter>
100<enter>
g<enter>

The int 10 will complete, the int 3 will return control back to the debugger
with a register dump.

later,
Larry E.
