Re: [Bug-apl] System Functions

Hi Alex,

IBM APL2 has debug variables ⎕L and ⎕R which
represent the left and right arguments of a user-defined functions.

In GNU APL, user-defined functions can have an axis argument and ⎕X
represents it,

I did not want to advertise ⎕L, ⎕R, and ⎕X too much because
they are not very well tested and were implemented only for
IBM APL2 compatibility.

I was unable to find a definition for ⎕X in 'info apl' or the IBM manual.
