Hello,
I'm dabbling in perl at work and really like it so far. I've
written several scripts lately. One I need to finish involves opening a
file ~17 GB. perl balks giving the following error.
'Value too large for defined data type at <name of script> line <number>'
large file handling seems to have been compiled into this version of
perl. output of perl -V

I'm using the 'open' function to open the file. Does anyone know of a
solution?
Thanks,
Jeff Rose
