[Bug-apl] behavior of )IN and )OUT with a library number

[Jeff Derby]

this is a follow-up to an exchange that's
in Bug-apl Digest, Vol 67, Issue 9, subject was 'trying to run gnu-apl
on a Mac'
the problem i had and reported was that
trying ')in 0 atffile', where atffile is a .atf generated by ibm ap2, gave
me ')IN 0 failed: No such file or directory';  but lib 0 seemed to
be pointing to the proper directory and the file was in that directory.

it seemed that the problem might be
with how i was associating directories with the library numbers.  i
went back and set up what's described in the gnu-apl info as a default
arrangement, with a library-root directory specified in the environment
variable APL_LIB_ROOT, with subdirectories workspace (so as lib 0), wslib1
(so as lib 1), etc.  and looking at the output from )libs seems to
confirm that this is all correct.  i can do ')load 0' and ')save 0'
against workspaces in the subdirectory set as lib 0 fine.  but if
i do ')in 0' against an atf file in the subdirectory i get the same error
as before (')IN 0 failed: No such file or directory').  But, if i
do ")in atffile" with the atf file in the 'workspaces' subdirectory
(so lib 0), the file is loaded correctly (and the ascii encodings used
for the apl symbols are translated correctly);  and if i do ")out
atffile" the contents of the active workspace are written correctly
to atffile.atf in the lib 0 subdirectory.  and this only works with
atf files in the lib 0 subdirectory

i have no problem with keeping all my
atf files in the lib 0 subdirectory.  but what i describe above is
not the way )in and )out are supposed to work
