No, you have to rely on perl returning errors correctly for failed system calls - unless you've just written some nuclear power station control scripts in perl - in that case let me know which power station it was and I'll remember to stay a few thousand miles away from it ;->

Any, back to the topic in hand - say perldoc -f print: 

print FILEHANDLE LIST
print LIST
print Prints a string or a list of strings. Returns true if successful.
If print returns false, that's good enough for me - the important thing is I know the data wasn't written - I can log $! and try to save the data somewhere else etc.

Camel pg 606 rightly bangs on about always checking failed system calls but it sometimes seems to fall on deaf ears :(
