Reading the file, non-slurp:
open IN, ...
chomp( my $data1 = <IN> );
chomp( my $data2 = <IN> );
chomp( my $data3 = <IN> );
chomp( my $data4 = <IN> );
chomp( my $data5 = <IN> );
while( <IN> ){
chomp;
...
}
close IN;
I don't know where people got the idea that reading a file one line at a
time is less efficient than slurping it. Both methods use the underlying
OS disk access system calls, where most of the efficiency lies. Unless
you can organize your data on disk to that advantage of more advance
methods, like ISAM or B-trees, just do it the way that makes the most
sense to the program.
Note that these advance methods take advantage of the data having a
certain structure. If your data does have this, these methods are slower
than the general purpose method.
