Re: [Bug-apl] ⎕FIO[1] behavior

[Juergen Sauermann]

Hi David,

thanks, fixed in SVN 827.

I believe the reason was that some ⎕FIO functions return valid positive integers but can also
fail (with an also positive errno). To distinguish between errrors and integer results I made all errors
negative.

I have now adapted ⎕FIO[2] to accept both positive and negative errno values.

I think that the behavior of ⎕fio[1] changed at some point. This is supposed to return the value of errno (a positive value), but now returns -errno, causing ⎕fio[2] ⎕fio[1] ⍬ to always return "Unknown error ...".
