Hi!

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 in the main procedure of a test program to get it working, and …

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 all out and write directly to the vram. …

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 the reading to terminate when it reaches a 00h character, switch to green …

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 call rol dx,1h four times...it's a …

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 make it jump to an address, rather …

Wasn't sure where else I was supposed to put this but I recently installed VMware and a copy of MS-DOS 6.22 using .img files mounted to a virtual drive in the virtual machine. I have a couple questions... 1. there is no "shutdown" command in this version of DOS, is …

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... moving things to and from the memory rather than using the stack, using memory addresses rather …

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 [code] ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz [/code] instead, it writes it in uppercase and then in lowercase again and again and again until I ctrl+c the program …

Without using MUL, IMUL, DIV, IDIV instructions and any iteration, find the product of 25 and a value in BL. save your result in DL . this is a task which i need some help in .. because i cant seem to figure how can we multiply without any iteration …

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 displaying both values, until both of them are equal... [CODE] 0 …

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 noticed that it was a LOT harder, and worked completely …

Hey, This is my first time on a VB forum so this may well be a long post, as there are many questions I've been wanting to ask over the years - sorry! Oh yeah, and I'm using VB6. 1) Is there a way to make "global" variables - for …

I can't find out if a form is in focus in my code. I have a form subclassed to catch an event that the form is being moved, so that I can have a separate form docked to it that moves along with it (without using a timer). But each …
