John,
.
Yes, ALL Z3 UTILITIES and some other programs which can use the ZCPR data
must be installed so they will be able to find information like the TCAP,
RCP, FCP, etc.	I'm not exactly sure why you are getting the error you 
reported.  DDT does reveal the error message early on in the file.  I'll
try to search for this address and possibly can figure the code and discern
the meaning of the message.  
 
You said you now have a path established.  When PATH executed, did you get
the named directory NAMES for these user areas as you programed them in
SYS.NDR?  For instance, my boot screen looks like this for the listed
startup command line:
 
 64K Heath/Zenith CP/M 2.2.04A 05/11/90
for H17 H37E DISKS  (units A thru F)
With option(s):  TOD INT BRK ZCPR3(ExWRFEChMFcNCS)
 PARALLEL DRIVER, 2/4 MHz Clock

Check your boot-up sequence against that above.  Maybe you aren't loading
the named directories and that is why you are getting the error.
 
Later, -- ken
nst that above.  Maybe you are
