fileexist(f)

[Petr M. <mi...@ph...>]

What do you think about adding function
 	fileexist("a.dat")
that would return 1 or 0 if file exists or does not exist?
I think there is a good chance this name does not clash with most user 
variables.

I have already needed that several times ... solution via `test` is not 
portable ...

The code is as easy as
   return (access(filename, F_OK) != 0))
see the attachment.
