Thread: Assembly Programming

you can do anything in asm, it just approaches impossibility

i know a little asm, mostly 8086 stuff. i've written a char to int translator and an int to char translator using nasm. that's the biggest i've gone.

i've got a question to the experienced ones: why does it take 5 bytes of code

Code:

mov ax,4c00h
int 21h

to do this:

Code:

int main() {
return 0;
}

which takes 12k of space?

A c program automatically links the c library. If I write assembly code to print a string using printf and linking in the c library I get similar executable sizes.

but this program doesn't link to any libraries

Most c compilers automaticaly link the standard c library even
if you don't include the appropriate header files or call the functions

It's not finished yet, but I'm doing my own assembler. http://www.geocities.com/CGIASM It shuld be up and running by the end of August.
