Subject: Size of ZCPR3 on disk

Actually, you can get a lot of benefit from just having Z3, the environments,
and a couple of utilities there. With the "standard" 1K overhead in
the BIOS plus the flow control package for really neat ZEX command files
All you need on your disk are LDR to load the environments, two environments
SYS.ENV, and SYS.FCP, IF.COM to handle IF's that the FCP can't and your
own DIR.COM. All told about 16K worth of stuff, and more if you replace
SUB with ZEX, no loss there. You get the benefits of multiple commands,
path searching, and a termcap for use when you are using some of the
other utilities. If you go over the list of utilities you will see a lot
of duplication in them, such as PAGE.COM and PRINT.COM, which are like
the resident commands TYPE and LIST. (more features but essentially the
same function) ERROR1,ERROR2,ERROR3,ERRORX are neat (you only need one
of the numbered error packages to handle errors and ERRORX to turn of
handling errors) If you use VMENU you don't need MENU, if you use 
SWEEP you probably won't need MCOPY, and if you aren't debugging or
something you don't need DU3 or MU3. Assuming you are the only one
on the system you probably wouldn't need WHEEL so when it comes down
to it, you really can everything you NEED plus some others for less
30K and practically everything with 64K. Not to bad really, especially
if it means you can get rid of some of the programs you currently have
on the disk, like PIP.COM or DUMP.COM. The only thing you might want at 
first but could later get rid of are the Help files for the utilities
you did have on line. I have a 180K  minifloppy that is nothing but help
(and it has space leftover) set aside as sort of a tutorial disk.
It really isn't as bad as you might think, the problem is all of
Ricks examples in the Documentation seem to have EVERYTHING loaded so
it looks like that is the Only way to have ZCPR3. This is definitely
not true.
