This is an interesting approach, to have the interpreter automatically
apply the typical memory allocation optimisations rather than you having to
do it yourself.
That said, I think it needs to be a bit more clever. There are many
occurrences where one appends a single element to a large array.
Thank you. I tried to use the -l flag for apl, but it says the argument is

I've added a function number 9 to the SQL library. This function takes the
name of a table and returns information about the columns in that table.
The function has no name in SQL.apl yet, because I am currently overseas
and my laptop has no Postgres, which means that it only works for SQLite so
I had never been able to get APserver to work properly, and particularly
not with the Unix Domain Sockets.
But, I finally figured it out. :-)
In the following call can be found in bot Svar_DB.cc and the APserver.

Hi Elias,
Unix Domain Sockets were your proposal if I remember correctly :-) .
They caused a few extra problems, for example select() does not
notice when a connection is closed.
Not sure which call you mean?

Also I have not found a reliable way to figure if a connection is closed

For example if I do *kill -9* of a process that is connected to *APserver*
then
*APserver* does not detect this in its *select()* loop.

In the latest version from svn, the file in swlib5 is still sql.apl. I was
under the impression that it would be installed as SQL.apl (but with the
file in src/sql still being named in lower case). I.e. that the case would
be changed as it's copied from src/apl to wslib5.

Postgres support for column listing is now implemented. You can pull the
latest version from Git.
Others: Please test if you have the chance. I came across to C++
incompatibility issues when moving the code from OSX to Linux. I think I've
fixed it now.

You use the monadic left-tack function. It's a variation of monadic

On Super-Shift-P we have the power operator ⍣. Its implementation in Dyalog
