well it's not a problem with TASM, since TASM compiled it fine and I unassembled it in DOS and all looked fine. At first I thought it was just the original problem, with the stack not unwinding, and...

thanks, it took me awhile to figure that one out, but it's fixed now. Any idea about the access denied error if the RET is at the bottom of the procedure?

so I figured out if I pop the stack into ax at the very beginning of the procedure (the return pointer), move that value into a variable I have saved, then push it back, then at the end of the...

haaaaallllpppp :(

---moar---
okay so, I SUPPOSE I could do something like,

outp proc

jmp stprc
fnprc: ret
stprc:

I was just confused as to the use of the functions and my code was a bit buggy.

after I called ah,03h int 10h, I needed to check that dh was not equal to 24d. If it was, equal to it, I had to...

so I have this working procedure that is basically like func. 09h of int 21h except it terminates at 00h, and it uses 01h-04h as control characters that determine the style of the text.

I wrote it...

nevermind, solved without help, bitches!

Sooooo I'm writing a program that involves a lot of writing to the screen and I want to do it at bios level. Mostly because the DOS calls can't do what I want to do, and also because I'm afraid to go...

yeah that seems right, also, I wasn't moving dx into al, I was trying to move the address contained in dx to al, "mov al,[dx]." I tried using si instead of dx and it seemed to work. Thanks.

so, I want to avoid using int 21h and start working with BIOS level code. I'm trying to write something equivalent to int 21h, function 09h, using int 10h functions 09h, 03h, and 02h, except I want...

I'm trying to output a hex value and TASM won't let me use any count on rotates and shifts other than 1. If I put rol dx,1h it works fine but if I put rol dx,4h it generates an error. So I have to...

okay thanks

how do I do it?

I'm trying to make a conditional jump to a label:

jz newmm

but tasm says that the relative jump is out of range by 000D bytes. How do I change this to a long jump? How can I...

ahh, I see

wat

this is pretty easy...
it's a 3 byte variable which contains a symbol (0x00CD, or a double-line similar to an equals sign used to make box-drawings in console applications), a space, and a...

wat

pardon me,
wat* do you have against void main()?

what do you have against void main()?

wat

still wondering...

also, when I compile a .com file with tasm and assume cs:main,ds:main,ss:main,es:main, then where does the stack go? I pushed "ABCDEF ab" to the stack and I just dumped the entire segment and can't...

I like writing assembly in debug under command prompt in windows, mostly because I don't have to worry about compiler rules and it's a lot better for learning how the processor works more in-depth......

I wrote a quick program into the memory using debug in an ms-dos prompt.
It should output the alphabet in uppercase, and then in lowercase, like so
...

add 25 times?

I'm playing with assembler trying to get it figured out and I wrote this program that was supposed to have two values, 0 and 10, and add to the 1 and subtract from the 10 and loop, each time...

Okay, so I'm well read in VB and quite an avid VB programmer but I realize that programming in visual basic isn't very marketable and above all I only use it for fun. I wanted to move to C++ but...

lmfao.
