What happens is that it tries to launch

While I agree that $HOME/.apl-history is more generally useful, I can
also make a case for having the history file's location be relative to
the working directory:

Thanks for understanding what I was saying even though I apparently have a
serious issue telling PATH and HOME apart. Whenever I say PATH, read HOME.

Dear Juergen,
If $HOME is there, why don't you default to $HOME/.apl.history rather than
just .apl.history? That would portably-enough solve the problem of not
getting .apl.history files all over the place. Just use whatever algorithm
you are using for the .gnu-apl directory.
Thanks.
Blake
Are you sure of that? I'm 99% sure that PATH is always set on OSX.

Hi Blake,
I don't have to. If I don't find $HOME then the preferences file in
$HOME is not read and
the /etc/gnu-apl.d/preferences file is read. If that file would use
$HOME then its purpose
of having a fallback in case $HOME is not working would be undermined.

Arguably, I can't think of a single situation where PATH isn't set while
getpwuid would work. I could be wrong though.

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.

Dear Juergen,
If you have trouble reliably finding the home directory, how do you find
the preferences file?
I would say to find the .apl.history file in the same way and place you
find the .gnu-apl directory. That would be consistent.
The problem I am having is that since I use GNU APL from th

Hi,
I have changed the rank operator with axis, i.e. ?[X].
The old implementation tried to improve on the somewhat broken
syntax specified in the ISO standard:
* A ?[y] B ??A ? y B*
* ?[y] B ??? y B*
The new implementation follows NARS which uses *?[X] *instead of *?*

Hi Blake,
yes. The problem with that is that it requires the presence of a home
directory.
There are use cases like scripting where the interpreter cannot figure
where the
home directory is located and my strategy is to depend on as few environment
variables (like $HOME or $PWD) as possible.
Dear Juergen,
Thanks. I can do that, but every other Linux program I have ever used,
although it may allow me to specify a config file location as you do, the
default is always in the home directory.
Thanks.

Hi Elias,
latest SVN? I fixed another issue in SVN 354 or so which caused execve()

The *apl -l 37* and *APserver -v* outputs would help.

Hi,
I have added monadic ⊣ and ⊢ see SVN 355.
Instead of making them identical I though it might be better to do
different things. What I came up with is this:

⊣ B also returns a copy of B, but as a committed APL value.
Thus ⊣ can be used (inste
