I have to agree with Blake here. Ideally there should be a call to
getenv("HOME") and if that returns non-NULL, then use the .apl_history in
$HOME/.apl/apl_history or something like that.

If it returns NULL, well, then fall back to current directory I suppose.

I could make the Emacs mode use the same file, so that th ehistory is
shared between emacs and non-emacs sessions.

Elias
