== More fun with CP/M Plus ==
Some of this stuff you probably know.. but anyway, in case you don't...
 
=== Faster loading of CP/M COM files ===
One of the first things you should do after setting your uIDE up is to copy all the CP/M program files to one of the IDE drives so that they load quicker.
* 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.
=== Public USER 0 (SYSTEM files) ===
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:-
* If you want to turn them back into normal files, enter the command SET *.*[DIR]
* If you want to list them, enter the command DIR[SYS] (note, needs the program DIR.COM installed)
 
=== Fast switch between any drive / user combination ===
One last info nugget, which you should find useful when looking through the download image. You can go to any drive / user combination by typing DN: where D is the drive letter and N is the user number. CP/M alters the CCP prompt to tell you where you are. For example:
 
A>C10:
10C>
 
Curiously, it puts the user number first. If you just enter the drive letter, it switches to the drive you specify, but leaves the user number unchanged:
 
10C>D:
10D>
 
When you are in USER 0, it does not show a user number in the CCP prompt.
