cd does not up-date the current working directory as reported by pwd:
Cartan:Applications:Tcl/Tk Folder 8.3.3:Build:
% cd "Cartan:Applications"
This error occurs on MacOS8.6, (on Blue and white G3).
The error does NOT occur on MacOS9.1 running on iBook2001
Version mac tcl/tk 8.3.3 downloaded recently from SF.
Nothing I've tried can reset the output of pwd to anything except the root directory once it has been changed from its startup value.
If I type
for a non-existent directory I get an error message, so cd is checking
to see if the directory exists. For some reason it must not
be updating the variable that informs pwd of the current working directory. The error might be in either pwd or cd.
