Re: 16 bit dos debug options?

I think there are several erros, but the first thing I don't like is
your first assuming AX contains the handle, and then changing AH
before moving what WAS the handle to BX.

;read the input file
mov ah, 3fh ;fn for reading           ; but just destroying AX in the
general case
mov bx, ax ;prev handle returned in ax, mov to bx for read   ; now BH
has #3fh
mov cx, BufSize ; bytes to read
mov dx, offset buffer ;variable that rcvs read-in
int 21h
jc Quit


This should have started
mov bx, inhandle
mov ax, 3f00h
