It's an example of a program that needs repackaging to run under cp/m 3. To use it, get CPM2RSX (or similarly-named RSX) and use the CP/M 3 utility to encapsulate a COM file with that RSX. That particular RSX converts cp/m 2.2-style direct bios io calls to cp/m 3 calls via the dos AND provides full physical->logical sector deblocking. However, as noted previously, you can't just put a zcpr3 cp/m 2.2 type command processor on the boot tracks of a cp/m 3 system and go; it requires rebuilding the interface from the ground up.
