#3 Related Linux File Channel issue (FID)

[Karl Tatgenhorst]

This is surely related to the other file channel bug I submitted (or I
have an odd expectation and there is no bug)

When I type A$=fid(1) I would expect a string identifying what is
open on the channel. I have managed a few times to get a file
open on channels 2-4 and each time I do A$=FID(2) for example
the outcome is A$=2 instead of the filename.
