     Yes - I use it on all the sites I personally support.  That is
where the recommendation to use install.pl came from.

    That would be what you wanted I would think.

    I think you have overlooked some error messages along the way that
were significant.  CPWD is not used in aips at this time - the
compilation of PWD in your $SYSLOCAL has failed and this error message
is the fall-back condition that results.

    There is no way that the install of 01 can replace the 00 files
unles the system names get messed up.  What is the version name in the
install.pl file you are using?  Is it the current file provided along
with the tar ball on the web site (128237 bytes dated Feb 15, 2002)?
Did the 00 LOAD area get updated with 00 code or 01 code?

    What does $AIPS_ROOT/AIPSPATH.SH say is the TST version, NEW
version?

    The most probably source of confusion may go back to the file
in your home area called .AIPSRC - look at it.  It may be best to
start over beginning with deleting that file.

BTW - I am leaving on vacation 5/12 so get back to me fast.
