Waterloo, Ontario Lines: 26 I am writing a profiler for the ST, everything is done except for a few crucial parts. When I get an address from the interrupt, I need to make it relative to the basepage of the currently executing application. As I see it there might be two ways of doing this. GEMDOS might possibly keep a pointer to the basepage of the currently running application, but I haven't been able to find one anywhere, or I can use Pexec in two stages, one to load the program to profile, (Pexec returns the load address in this mode), and then use Pexec to execute the program. There is one problem, though these various modes are mentioned in the Atari Docs, they are not fully documented. The reader is referred to the 'Pexec Cookbook', which according to Atari Canada, does not exist. As of yet, I have not been able to get this method to work. Neil, Landon ? Comments ? Any insight on this would be appreciated. I will post the profiler to the net when it is finished. David Rowley Looking Glass Software Waterloo, Ontario ...!utzoo!watmath!looking!david
