With reference to my Ultimate in Pexec problem: I probably didn't make myself clear about how I wanted to execute the program. I want to double click on a loader program that will load the main program, relocate it, restore the default system vectors and memory move it if required. Also I don't want to know what the vectors are now but what the system would like them to be. Event driven software invariably grabs vectors and bombs this weird program. In effect how do I give a program a boot-up like environment without the boot? I guess I always go for the impossible. Speaking of which: Neochrome uses screen interrupts to get more colours on the screen & The Pawn (Magnetic Scrolls Graphic Adventure) uses them to mix low and medium resolution modes on the screen. I have done both but would like to use this technique to create segmented video ram ie. Non continuous video RAM. Anyone got any ideas?
