- Two CDPs At Once
- ----------------
-
- You can run two copies of CDP at the same time!!
-
- The 2nd copy of CDP reverses its right-left orientation of the screen
- from the first one, and uses the two hot keys that the 1st one does not.
-
- For (a good) example, just do:
-
- >SET CDPSWAP=E ; so that the CDPs will swap on disk E:
- ; (not needed if you have enough EMS)
- ; (& if you have no E:, C: or D: will work)
- ; Without this statement, EMS or C: is used
- ; by default. It is best to use a small
- ; disk partition (or a ram disk) that is not
- ; very active for the swapping. This prevents
- ; CDP from having to reload disk usage
- ; information because of its own swapping.
- ; (Note: that situation occurs infrequently
- ; anyway, since the invisible CDP swap files
- ; normally remain a constant size in a fixed
- ; disk area).
-
- >CDP +C ; after CDP comes up, hit ^Q to make it go resident
- Then do
-
- >CDP +D. ; the +s make sure CDP comes up on the proper disk
-
- (If you have the shareware version that goes
- resident and does not come up immediately, you do not need to bring up the
- first one before running the second one. Similarly, if you did CDP with no +,
- you may install the second one before bothering to bring up the first.
- Thus, you may install two copies of CDP simultaneously in a batch file with
- no problems. It also does not matter which of the two copies you actually
- bring up first.)
-
- Both CDPs will go resident. The first logged to disk C, and the
- second to disk D. Either one may be brought up by hotkey over top of the
- other, in any order.
-
- If you are using the default hotkeys (not changed by CDPRENAM),
- the first CDP will respond to Lshift-Lshift and Rshift-Rshift (to come
- up in the currrent CDP-logged directory or current DOS-logged directory).
- The second CDP will respond to Ctrl-Ctrl and Alt-Alt in the same fashion.
- Whatever two hotkeys you have assigned to the first CDP, the second one
- will use the other two. You must use the "left" hot keys (lshift-lshift for
- the 1st CDP and ctrl-ctrl for the 2nd) to bring up CDP on the disk indicated
- on the command line; rshift-rshift or alt-alt come up in the current DOS
- directory, whichever disk it may be on.
-
- Now, when you wish to work on disk D after working on Disk C,
- you do not need to LOG from disk C to disk D. Just hit the hotkey of the CDP
- that is logged to disk D. This saves both the time of logging, and the
- loading of information on disk D that would otherwise be neccessary. The
- copy of CDP that is logged to disk D already has that information! And
- can pop up instantly!!
-
- Also, if your disks C: and D: are actually separate partitions of
- the same physical disk, the CDP on C: will let the CDP on D: know that
- writes on C: do not affect the information already held by the copy logged
- to D:. And vice-versa. (At the low level that CDP operates, a single copy
- of CDP knows only that something written by some program other than CDP has
- written on a PHYSICAL disk -- it cannot distinguish disk C: from D: unless
- CDP itself is doing the writing).
-
- This enables you to work on your disks faster than ever! Previously,
- if you used CDP for moving, copying, etc., on two disks; then you had to
- relog from one disk to the other, necessitating reloading the directory of
- the newly logged-to disk. This is no longer necessary. The second copy of CDP
- is already there and ready for instant use on the second disk!
-
- One note of caution. When removing CDP from memory, you must remove
- the second one first!
-
- Also remember, because it can be confusing, that if one CDP is
- already up (& showing on the monitor), and you bring up the other one via
- its hotkey; then when you take the 2nd one down, the one that was previously
- up will come up again automatically; and you must also do a ctrl-Q or QUIT
- to make it go down and ultimately get back to the DOS or application level.
