AN INTRODUCTION TO ZCPR3 FROM THE USER'S PERSPECTIVE
by Richard Conn
The ZCPR3 System is a collection of programs based around
the ZCPR3 Command Processor. Forming an integrated system of
tools, the ZCPR3 System offers a number of convenient and
sometimes more user-friendly features to the CP/M 2.2 user.
Maintaining CP/M 2.2 compatibility at all times (all known
commercial CP/M 2.2 programs run under ZCPR3 without
modification), the ZCPR3 System brings to its users a variety of
tools which conceptually implement features found in other
operating systems, including TOPS-20 (1), UNIX (2), NOS (3),
MULTICS (4), and VMS (5), and tools which implement features
unique to the ZCPR3 System (to my knowledge).
This Introduction is intended to outline some of the key
features of the ZCPR3 System from the user's perspective. More
complete technical details of implementation and use will follow
later. Knowledge of CP/M 2.2 is assumed, and some experience
with ZCPR2 is useful, in order to understand the following
presentation in detail. The major features of the ZCPR3 System
which are described in this Introduction include:
o Directories o Wheel Users and Passwords
o Command Lines o Command Processing
o Resident Command Packages
o Flow Command Packages
o ZEX Command Files
o Error Handlers o Aliases
o Shells o Z3TCAP
o Variable o Screen-Oriented Terminal
o MENU Configuration
o VFILER
o "Secure" Systems
