just eyeing one not yet mentioned detail very sceptically and late at night:
Is it just me or is $file in the stated sub ReadFile indeed identical to 1, assuming ReadFile itself was called correctly with one argument... ?
Fix with e.g. my ($file)=@_
(if you followed ikegami's pointers, you should have touched&fixed that one already, right?).
Good - you've seen & done it already, I should have reloaded the thread before creating the node :).
