Here are PUSHD and POPD, two utilities that I find often come in handy. PUSHD
of course saves your current directory in a directory stack, and POPD pulls
off the last place where you were. The directory paths are stored as lists
in a list called DPATH, which you must create in the root directory.
( HOME {} 'DPATH' STO )
I hope you are using the HOME-MAIN utility management method; put the programs
in the HOME directory. If you're stingy with memory, kill the error message
from POPD - remove everything between DROP and END.
@ PUSHD - push current directory
%%HP: T(3)A(D)F(.);
\<< PATH DUP 1 \->LIST
HOME 'DPATH' STO+
EVAL
\>>
@ POPD - pop directory
%%HP: T(3)A(D)F(.);
\<< HOME DPATH OBJ\-> DUP
IF
THEN 1 - \->LIST
'DPATH' STO EVAL
ELSE DROP
"POPD Error:" 1
"Directory Stack Empty"
