surfaces onto 2 separate disks. However, if you have a 1571 you
will find it convenient to copy both surfaces onto a standard
double-sided disk: after copying the first side, turn over the
original disk and copy the second side onto the same destination
disk by again entering the copy instruction in response to the PIP
prompt.
You may sometimes want to make disks that just have the
system files on them. To do this use PIP to copy the files
CPM+.SYS and CCP.COM to the newly formatted disk. NOTE:
Only disks that you intend to use to boot CP/M need these 2 files
on them - putting them on other disks wastes space.
With a single drive, enter E:=A:CPM+.SYS to copy the first file
and then E:=A:CCP.COM to copy the second file.
When you have finished using PIP, press RETURN to return from
the PIP prompt to the system prompt.
A full description of PIP can be obtained by entering HELP PIP,
HELP PIP OPTIONS and HELP PIP EXAMPLES.
LANGUAGES & APPLICATIONS SOFTWARE
CP/M is just an operating system, that is a means to an end - not
an end in itself. On its own it does not do anything useful. If you
want to write your own programs you will need a language, either
assembler or high level, in which to write them. If you want to play
games or do business work you will need applications programs.

What to Buy

Because CP/M has been implemented on almost every
computer ever designed that used the Intel 8080 or the Zilog Z80
cpu, there is a very large amount of software available for running
on CP/M systems. The most comprehensive catalogue of
commercial software is the 'CP/M Software Finder' published for
Digital Research by Que Corporation and available through good
software retailers (ISBN 0-88-022-021-X). Since it is not
convenient for the CP/M Users Group to supply its library on
Commodore format disks, a selection of public domain CP/M
