So far, trying both dialects while learning has illuminated some concepts
for me, but I fear I might confuse myself with implementation differences.
Again, thank you very much for the insight.

Hi, reading GNU APL documentation, in the section 2.7 "2.7 Direct Functions

It states that lambdas do not support multiple expressions (amongst other
features). If this is the case, what purpose does allowing local variable

Allowing

I have noticed what I believe are some inconsistencies (bugs?) with how GNU

versus 'lambda fns'.
Consider the following )DUMP file:

Hello,
Please see below a small patch proposal for a new configure option to move
the ^D (EOT) behaviour to a different key (^Z which is currently
unassigned), which allows keyboard ctrl-D to act as delete-char.

What is the general consensus among GNU APL users here on the newer 'tacit
style' that seems so prevalent in many online APL resources nowadays?

As a new, inexperienced APLer, exploring a bit more with GNU APL, I wonder
if it discourages people new to APL to find, as I

It seems a tenuous place to publish such a useful resource, within a sample

I noticed tonight that the jot (∘, Compose) operator is only indirectly
mentioned in GNU APL ]HELP. Unlike most core APL symbols GNU APL doesn't
output anything for ]HELP ∘
However, looking at the source code it appears that this pseudo-operator

Hi, doing some experiments in learning APL I was writing a word frequency
count program that takes in a document, identifies unique words and then
outputs the top 'N' occurring words.
The most straightforward solution, to me, seems to be ∘.≡ which works up to
a certain dataset size. The main
Hi Hans-Peter,
do you mind if I post a cleaned-up version of your solution to the word

That was the original motivation for my attempting a solution, as there was
no APL example yet posted there.

Hi, while investigating using GNU APL for scripting (--script), I have two
questions:
1) Is there a way to specify an exit code in APL scripts? I didn't see any
⎕FIO or system call interface to invoke the host OS exit() with a code
other than the implied 0 code in GNU APL's source function

Hi,
I recently pulled latest svn and saw these strange messages right after the
GNU APL banner. Backing up, it appears to have begun with r1616 for me.
I did a `make clean` and fresh `./configure` for each build to narrow down
when the issue began.
