1. Get Open file size

How can I get file size/file length of opened file in eu?
In VB I can use LOF(fn). By using dir() I only get size when the file
last closed.

as I'm coding an entire library for random access files, i think know this one.
you can perform a seek command on the open file that will put the file pointer at
the end of the file. then read the file pointer again and you have the current
size. use code similar to this.
-- UNtested code follows
fn = open("data.fil","r")
-- puts pointer at end of file
tempatom = seek(fn,-1)
-- error handling for tempatom goes here
-- now get the current file pointer
filesize = where(fn)
