- ZCCP has been improved slightly from the original release. It
- should run much the same as before however modifications have
- been made in an attempt to allow it to work successfully from
- systems which boot from other than the A: drive. Also, the
- terminal dimensions are now automatically taken from the SCB (as
- set up by GENCPM). Special thanks go to Randy Winchester who is
- sharing his easy to follow instructions about ZCCP. Read ZCCP.TXT
- in this package for the expert help.

- ZCCP Quick Instructions
- =======================
-
- ZCCP is a direct replacement for the CP/M 3.0 CCP. It requires
- ZPM3 and provides a ZCPR compatible system. There are some minor
- incompatibilities with ZCPR however the advantages of ZCCP more
- than outweigh these.
-
- You must replace your current CCP with the ZCCP.COM. How you do
- this will depend on the setup of your computer so no details are
- given here.
-
- When ZCCP starts, it reads ZINSTAL.ZPM (which must be on the
- default boot drive (usually A:) in user area 0). This file can
- be patched to set initial values for MHZ (speed of the computer),
- MAXU (maximum user number) and MAXD (highest disk drive). These
- values are set near the start of the ZINSTAL.ZPM file and there
- are ASCII pointers to them (which can be seen with a debugger
- such as SID.COM).
-
- After ZINSTAL.ZPM has been read, ZCCP attempts to run the command
- STARTZPM.COM. This is usually an "alias" containing a number of
- commands used to put the system into a useful state. Typically
- STARTZPM.COM would contain commands to load a TCAP and named
- directory file, to set the path, and to set an error handler.
-
- LOADSEG.COM is a ZCCP utility used to load RSXes, TCAPs and Named
- Directory files. It contains some online help.
-
- RSXDIR.COM is a ZCPR utility which displays RSXes in memory. It
- has been included to help you understand how LOADSEG places
- various segments in high memory.
-
- DISKINFO.COM is a ZCPR utility which gives information about your
- disks. It has been included for your interest.
-
- Note that ZCCP has very few resident commands. If you are
- switching from a standard CP/M 3.0 CCP you will find that you are
- unable to perform certain simple functions (such as directory
- displays!). You should therefore obtain replacements for the CCP
- resident commands before installing ZCCP. The Z-Node bulletin
- boards in Australia and the USA are a good source. Note that ZCCP
- will not load Type-4 ZCPR programs.
-
- If you are familiar with ZCPR systems you should have little
- trouble in getting the most from ZCCP. If you are new to ZCPR, I
- suggest that you learn as much as you can. ZCPR is a complex and
- powerful system which does very little without proper setup.
-
- RCP's and IOP's are not implemented (which saves TPA space) and
- FCP's are not implemented although flow control is. To use flow
- control you must have an IF.COM program to handle IF commands.
- ZCCP handles the standard flow control commands internally (XIF,
- FI, ELSE, AND, OR). There are two other internal commands
- implemented: NOTE (a do-nothing command) and CLS (to clear the
- screen).
-

- The ZCCP package presented here may be freely distributed and
- used for your own private use. No commercial or institutional use
- is allowed without prior written agreement.

-
- The Z-Node 62 BBS in Perth, Western Australia may be contacted
- from Australia on 09 450 0200 or from overseas on +619 4500200.
- Z-Node 62 also is a distribution point for ZPM3 and MYZ80. MYZ80
- is a high performance Z80 emulator for IBM AT (and better)
- computers. MYZ80 is able to run ZPM3.
-
-
- No support for ZCCP is being offered at this stage. Use at your
- own risk.
