Message-ID: <1990Nov30.161424.2348@uoft02.utoledo.edu> Date: 30 Nov 90 21:14:23 GMT Organization: University of Toledo Lines: 19 I wrote an assembly program for my c128. Its a simple program that writes the time on the screen in the upper left hand corner. To be useful, it is started by a sys statement and returns basic when finished. It uses the cassette buffer as its home. I want to have the C128 to execute this program as part of the C128's normal routine so I don't have to keep sending a sys command. is there a way to patch something the normal operating routine that will cause the computer to JSR to my routine and then RTS back to what ever it was doing, without interupting any basic programs that may be executing at the same time? I am new to assembly so if anyone know the answer, please, I beg you, in every day terms!!! :) Thanks in advance Tony. PS. If anyone wants the basic prg that sets the clock and the ml program that is the clock, the are uploaded to my account and I can send them out uuencoded!!
