@meynaf: the setfont commad DOES what I wanted!!! Thanks!!!
Whats the maximum size for the TOPAZ font? Is it possible to, lets say, put the MS-DOS font on it for fun? Or other mythical fonts..
Also, do you know how to disable/hide the mouse cursor? There is this small program (
http://aminet.net/package/util/mouse/MouseOff) but it does nothing from AmigaDOS in 3.1. Maybe there is a simple C or ASM sequence for hiding the mouse that I can compile with SASC?
