I have found the only way to reliably start assembly programs is to use the startup code in the back of the Rom Kernel Manual, specifically you must first initialize a variable called "SysBase" to the contents of location AbsExecBase ($4), then you must open the dos library with MOVE.L #dosname,A1 MOVE.l #0,D0 CallSys OpenLibrary And then you can do whatever else you want. But without these two, and in that order you can't do anything. -- --Chuck McManis uucp: {anywhere}!sun!cmcmanis BIX: cmcmanis ARPAnet: cmcmanis@sun.com These opinions are my own and no one elses, but you knew that didn't you.
