Re: Lua, testing whether a file exists...

[The Doctor <the_doctor@...>]

Thankyou.
That works.
I was using io.open within another function and overlooked the effect that was having..
(F=assert(io.open(F,"rb")))
It works fine with the file there, and I'd forgotten that io.open wasn't being tested directly anymore..
Sorry everyone, too many hours don't help me think well.
