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).

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?
