        Sorry about the inconvenience with CHDIR.  I have  really
considered  the  need  of  CHDIR to write itself back out to disk
somewhat of a cludge, and have already designed a new CHDIR which
runs in the ZCPR2 environment.  Am really hoping to get ZCPR2 out
before Christmas, and, unlike ZCPR1, ZCPR2 is coming with a whole
set  of  utility programs (probably 30 or 40 before I'm finished)
which are intimately linked to each  other.   CHDIR  and  CD  are
parts  of  the  heart of the system, and CHDIR now creates a file
containing the directory names rather than storing them internal-
ly.

        The reason for this is that ALL of  the  ZCPR2  utilities
will be supporting a named directory structure, based on the file
created by CHDIR.  Examples:

                XDIR JEFF:*.COM

                ERASE ASM:*.TMP,MYWORK:*.ASM,HELP:*.*

                MCOPY BACKUP:=WORK1:*.SRC

        As you can see, ZCPR2 offers quite a  difference.   Also,
anywhere  you  can  use  a  named directory, you can also use the
disk/user form:

                XDIR B5:

        For those considering using CHDIR, you may wish  to  wait
until after the ZCPR2 release.

                Rick
