Hi,
Just for extra information, I am interested in understanding how the
if (grep length == 0, @arrayname) works.
Or perhaps I could be pointed to some documentation ie perldoc where i
could find out more about is it the length function? works.
thanks,
radhika

chomp;
print ERRLOG 'Blank line' if $_ eq '';
