Hi Peter,
Unfortunately this doesn't work either, the only way to get it to read the
DOS file properly on WinXP is not to set $/ at all, but of course this
breaks the other platforms
Anyway, I have rewritten it to use sysread to read a chunk at the top of the
file (I only need the header of the file) and process that with a split and
foreach, which seems to be working fine!
Thanks for your help
Adam
