[comp.sys.ibm.pc] Pushd/popd for PCDOS 3.3

davej@entropy.ms.washington.edu (Dave Jenner) (11/10/87)

	About a year ago I got off the net binaries for "pushd" and "popd"
for the IBM PC.  They were v2.10 dated 2/8/86 and were posted by
Michael Tsang (gumby!g-tsang).  I have used them routinely ever since.
They are wonderful!

	However, I just recently converted to PC DOS 3.3, and something
seems to have broken.  First, the DIRSTACK environmental variable does
not appear in the environment (with a "set").  Secondly, I am able to
pushd ... pushd and then popd ... popd if I DON'T run certain programs
in between.  Apparently, the mechanism for putting the directory stack
into the environment no longer fully works in PC DOS 3.3.

	Has anyone else encountered this problem?  Are updated versions available?
Are the sources available?  Any help that anyone could give would be greatly
appreciated.  None of the machines in .washington.edu seem to be able to
deliver to the original author.  Thanks.
