John,
.
You'd think that I would have no problem reworking ZCPR3 since I've
installed it on three of my machines, the H-89, Z-90, and Z-100.  I
mentioned that I was going to setup a Z80DOS system (BDOS replacement).
Well, I got the BDOS kernel OK and made the BIOS modifications.
Everything assembled with only a couple of backtracks to fix typos.  Then
I needed to rework the ZCPR3 packages.  Updated Z3BASE.LIB and
reassembled ZCPR and the packages.  Moved the CCP into place with no
problems.  Booted the system with the new packages and some things just
did not seem to be working right.  Well, I sat here off an on for about
an hour tonight trying to find where I goofed.  Checked the Z3BASE.LIB,
--OK.  Peeked memory, and found the Environment package at the wrong
address.  Recognized the address as the address of the original system.
Checked Z3BASE again!!!  Still OK.  Checked the STARTUP.COM, but that
would show up in the CommandLine package.  Then it hit me.  I did not
reinstall LDR.COM and PATH.COM with the new ENVIRONMENT address.  Since
the installation patches in the Environment address, and since these
modules were installed for the OLD system, LDR would load the environment
in the wrong place, and Path could find it OK.  But when I tried
something else which needed the environment information, it said it was
not there.  This first showed up when I tried to use LAP.COM to setup a
new startup command.  I ran Z3INS on LAP and then ran LAP.  It said it
was not installed.  (I just did it!!!!  Of course, it's installed..)
Since it did not find the environment at the patched-in address, it
reported that it had not been installed.
.
Sooo, don't forget to install each Z3 utility before you run it...
.
BTW, as soon as you get the system up and startup loads the packages
correctly, you will want to get LAP.COM and run it.  This really speeds
up loading the packages and init commands.
.
I guess you are just about at this point now.  I'll try to start putting
some stuff together on the utilities I like.  When we get these going,
maybe you can help me figure out more about ALIASES.
.
Later, --ken
