/* Console Output */
CPM2.2 doesn't use any extra memory, and since it runs in configuration 'C0' accessing extra memory is much quicker and easier than under CPM3.0.
You should ensure your code (within the TPA) is in a safe region (0000-3fff, 8000-ffff), you can then page in the memory and copy it out to your destination directly as long as the destination is also within the safe area. It is much safer and simpler to use.
NOTE: This can't be used on other CPM2.2 variants on the CPC.
==== Console Input ====
==== Console Output ====
Console output (via BDOS functions) ultimately uses TXT OUTPUT so executes has the potential to execute firmware control codes and displays display CPC firmware characters. However, BDOS function 2 (Console output), which has control before TXT OUTPUT, looks for some specific characters and will perform specific processing regardless of whether it is part of a control character sequence or not. Fore example, Console Output looks for TAB (&09). Therefore use BDOS function 6 (Direct console input/output) to avoid this processing. With this function you can use the control codes to define windows, change modes, change colours etc.
