3. The control C and %ex/ exits return to the SELECTED Monitor. Normally these take you back to CP/M; If you have used CPMSET the Selected monitor will be CP/M, if you use ZAPSET, then ZAPPLE is invoked. You may change these by changing the contents of location 100D and 100E to reflect the location you wish to reach on a control C or %ex/ function. 4. To get back into SAM after either a control C or %ex/ function - if in your monitor then G to 100, if in CPM execute the zero length program called REE for Reenter. If you use ZAPSET, the normal Zapple monitor IOSET and IOCHK functions will be invoked. If your CPM system sustains the appropriate BDOS calls then all is well. If you have peculiar CBIOS conditions then you can cause automatic initialization whenever entering or reentering SAM by placing the adress of your INIT program at ^H102B and 102C. .
