I hope this doesn't sound too stupid, but is it possible to easily change the text size, or 'font', and the number of lines per screen and characters per line, so that I can fit more text into a full screen in a DOS environment? Question

example:

Code:

xor ah, ah  ;set video mode
mov al, $xxx ;the video mode you desire
int $10

$03 should provide a 640xXXX screen resolution

for more information see INTERRUP.A of the ralf brown interrupt list, or int $10 of the html version

or http://www.ctyme.com/intr/rb-0069.htm specifically for set video mode

here you may also set graphics mode (to draw pixels) which i think you also requested in an earlier thread

Thank you for rbrown link. It seems that there are many more int's than I was aware of. I shall experiment with these. Hope that the ones that I want work!!
Very Happy
