NZ-COM version 1.2 includes two changes of significance. First, due to an �
oversight, when version 1.0 was told to load a new ZCM or ENV file for �
which no new modules had to be loaded, it also failed to update data in the �
environment, such as printer characteristics, maximum drives and users, and �
so on. It will now do so.
The second change was in the safety checking performed by NZCOM.COM to make �
sure that it was being requested to load a version that was consistent with �
the underlying CP/M system. This check turned out to be stricter than �
necessary and was preventing NZ-COM from running on some systems (e.g., �
Lobo Max) that, in fact, could support it quite nicely.
---------- NEW FILES: NZCPR.LBR, NZFCP.LBR, NZRCP.LBR
The main NZCOM.LBR now contains only the standard configurations of the �
CPR, FCP, and RCP modules to minimize disk space requirements. Alternative �
versions of these modules are now supplied in separate libraries. Modules �
can be loaded directly from these libraries, or individual files can be �
extracted and put into NZCOM.LBR to replace the default files. Each �
library has a brief DOC file describing the modules (one of which is the �
default version included in NZCOM.LBR).
---------- NEW PROGRAM: ZEX TYPE 4
Named ZEX4.COM in this release, this is a new version of ZEX with many �
features not seen before (See ZEX4.DOC). This program is brand new and may �
well exhibit one or two un-planned 'features'. Please report any problems.
---------- TCSELECT PROBLEM
�A problem has been discovered with the operation of TCSELECT as described �
in the manual. TCSELECT is a Z-System program and does not function �
reliably under CP/M (on some systems it causes a crash). Fortunately there �
is a simple fix: reverse the order of the instructions in the manual. Boot �
up NZ-COM before attempting to create MYTERM.Z3T, and run TCSELECT only �
after NZ-COM is running.
---------- ERA.COM, REN.COM, SAVE.COM, ETC.
The standard configuration of Z-System does not include resident commands �
for REN, DIR, or SAVE. These are provided instead as transient programs �
(COM files), and you should copy any that you need to your working disk. �
Several other functions that are often resident (but not always) are also �
provided as COM files. Many of these are type-4 programs (see the manual). �
We recommend using SDZ.COM as your standard directory display utility. It �
is far more functional than the resident DIR commands in either Z-System or �
CP/M, and it is designed to work properly under both.
---------- EASE PROBLEMS
There are unfortunately serious defects in the coding of EASE. On many �
computers EASE appears to work without problems, on some it crashes �
completely, and on others it works but causes other strange behavior to �
occur. We tried using it on a Kaypro with the K-ROM (?), and as soon as we �
loaded ease we started to get BIOS errors on disk reads. We hope that the �
author of EASE (or someone else) will discover and correct these problems. �
The program is so nice conceptually. Use it with caution.
---------- VLU VERSIONS
We forgot when writing the manual that VLU, like ZFILER, has two quite �
different versions depending on whether your terminal uses reverse or dim �
video for highlighting. Therefore, you will find on the release disk VLU-�
REV.COM and VLU-DIM.COM. Copy the appropriate one to your working disk �
under the name VLU.COM.
