Title: print a number
Post by: nobody on December 20, 2007, 06:40:59 PM

hello,
i'm wondering how to simply print a number on the screen !
-first when it's in a register
-second when it's in memory (in .bss i suppose)

Wrong forum.

> -first when it's in a register

Set up a limit (maybe 999 for start), set up a string buffer, fill it with "000" , start trying to subtract 100's from the register, for every successful subtraction increase the digit in your buffer, when 100's are done, move to 10's, finally just copy the 1's ;-)

Load into a register ?

YES. Works. It had some MA$M junk inside, however -> fixed:

Note the 7-times smaller EXE size (COM would be even smaller) - the war on bloat must go on :-D
