Re: [Bug-apl] Documentation/examples on system functions

[Juergen Sauermann]

Hi Alexey,

The majority of GNU APL functions and commands are described in the IBM
APL2 documentation which is available on the web. That documentations is better
than anything I could possible write, so I did not even try.

The functions that are only in GNU APL are supposedly contained in the info system
and can be accessed with the shell command

info apl

⎕FIO is somewhat special because it contains many functions that are already described
as man pages for the corresponding C library functions. You do not need
an intentional error in ⎕FIO; to show them. Just try:

⎕FIO ''

or:

⎕FIO ⍬

to display the functions. This is described in chapter 3.9 "Native Functions" of info apl
(⎕FIO used to be a native function before it was turned into a system function).

Best Regards,
Jürgen Sauermann

Hi,

I'm missing any information on system functions.
The 'official' documentation only explains handful of functions.
The ]help command just lists the functions.
For example FIO function I had to type it with the intentional error in
the argument to get the list of possible options (!!!)
I can't find anything on FX for example.

Where could I find documentation on system functions, how to use them,
any examples?
