GEMDOS *is not* reentrant. If you are not using a semaphore on your GEMDOS calls, you *will* crash the system if it is called reentrantly. BIOS and XBIOS are only reentrant to 3 levels, so you are safe there, but you should still have some kind of 'counting' semaphore. - mike vederman Double Click Software -- ------------------------------------------------------------------------------ Double Click Me | Double Click Software | P.O.
