If you modify the wrong area of memory you can cause other programs to fail and they will have a difficult time figuring out what happened. The general practice is to go into KEY0 for only the specfic instructions that you need. Then go back to your normal KEY. MODESET KEY=NZERO . Of course Key0 does not bypass page, segment or low storage protection. You need to monkey with CR's or use real storage addresses. -- Binyamin Dissen <[email protected]> http://www.dissensoftware.com Director, Dissen Software, Bar & Grill - Israel Should you use the mailblocks package and expect a response from me, you should preauthorize the dissensoftware.com domain.
