Hi Roy,
very nice work, indeed.
I would recommend that you (and everybody else running GNU APL
on the public internet) ./configure your GNU APL with:
./configure SECURITY_LEVEL_WANTED=2 ...
That should prevents a number of GNU APL facilities such as )SAVE workspace,
SQL, ... (see Security.def for a list of facilities that can be
disabled) from being
executed and harm your server.
Or use SECURITY_LEVEL_WANTED=1 and disable individual facilities in a
profile
in one of the GNU APL preferences files.
Best Regards,
Jürgen

Hi, trygnuapl has a new, permanent home.
The trygnuapl service https://trygnuapl.github.io is an online,
interactive
web browser-based interface to the GNU APL interpreter, in the spirit of
Dyalog's Try APL service https://tryapl.com
Version 1.1 (July 2025) https://trygnuapl.github.io
Version 1.1 user interface and other enhancements are described on the
project page https://github.com/trygnuapl/trygnuapl.github.io
I pledge to keep this hobby running for as long as Google* Cloud Platform
(GCP) graciously offers a free tier and trygnuapl usage is within or near
the free tier threshold for Cloud Run which, as of 8/15/2025, is:
2 million requests per month
360,000 GB-seconds of memory, 180,000 vCPU-seconds of compute time
1 GB of outbound data transfer from North America per month
* no affiliation, just a (so far adequately satisfied) hobbyist-user.

Hi,
For fun, I coded a browser (Web) interface for GNU APL.
https://roytobin.github.io/trygnuapl/
The service, by intention, imposes minimal
restrictions/limitations on
functionality. Yet memory and network usage are limited, like
Dyalog's
tryapl.com <http://tryapl.com>. So best results are had when
using modest-sized datasets.
