III. USING THE PSEUDO DISK

After the PSEUDO DISK has been installed, it is accessed

just like another disk drive, using the drive designation

assigned to it (default = C:). Files can be transferred to and

from it using standard file copy programs such as PIP.

In fact, a submit file can be used to:

1. Install the PSEUDO DISK.

2. Copy several files.

by using a single command.

FOR EXAMPLE, the following submit file, XFER.SUB, will

install the PSEUDO DISK (Drive C:) and then copy files from Drive

B to it simply by typing, SUBMIT XFER.

------------------------------------------------------------------

file XFER.SUB:

INIT

PIP C:=B:*.*

IV. LIMITATIONS AND REQUIREMENTS

1. The CP/M PSEUDO DISK will utilize up to 256K of RAM in

the form of SATURN 32K, 64K, or 128K RAM Boards as well

as 16K RAM Boards.

2. The PSEUDO DISK driver routines reside in the portion of

the I/O configuration block reserved for user I/O

Driver Software. As a result, this space is unavailable

for user drivers after the PSEUDO DISK has been

installed.
