/* More fun with CP/M Plus */
* Add the line C:SETDEF M:,C:,* [ORDER = (SUB,COM)] and save the file
* What this does is make the CCP (command line processor) look for SUB and COM files on the IDE drive C: before the currently logged disk. So if you are on A: and you issue the command BASIC (to load BASIC), it will be loaded from the IDE drive rapidly, even if there is a copy on A:. In fact, it looks on M: first, and a submit file like BASIC.SUB takes precedence over the real executable BASIC.COM.
 
Another useful trick is to make the CP/M COM files in user area 0 into SYSTEM files. This means that they won't be visible when you do a DIR, and they will be executable from all user areas on the same disk. So:-
 
* Go to the drive where you copied all the COM files to. In this example, it is C:
* Switch to USER 0 (type "USER 0" at the CP/M prompt).
* Enter the command SET *.* [SYS]
* Now, when you switch to another user on the same drive, you can access the CP/M command set without copying them to the user area first.
* If you do this, there's no need to copy PIP to all the user areas (this was required for CP/M 2.2).
