I'd suggest writing a subroutine to read all your configurations into an array, and then when processing the input file you can simply load the current configuration. Something like:

my @configurations; load_configurations("config_file"); open my $FH, '<', $input_fname or die "Can't open $input_fname: $!"; while (<$FH>) { my @config_vars; ... parse out an input entry ... @config_vars = @$configurations[$configuration_ID]; ... code to process input using configuration variables... } sub load_configurations { my $fname = shift; open my $FH, '<', $fname or die "Can't open $fname: $!"; while (<$FH>) { my @config_vars; ... parse out a configuration... $configurations[$configuration_ID] = [ @config_vars ]; } }

This way, you have all the configurations at your fingertips, and you can process each input entry with a different configuration, if desired.


When your only tool is a hammer, all problems look like your thumb.

[Discipulus]: I havery limited needs in such field. Sometimes (for children party invitations) i draw something by hand and I scan it to include into an ms doc.
Discipulus havery can be a good neologism for: have very..;=)
[ambrus]: Discipulus: sure, it's just that, look, some people (including me) have such unreadable and slow handwriting that writing an article or slides by hand would be a very bad idea.
[choroba]: it might bery useful for other verbs, too
[ambrus]: (and I have a need for at least decent formatting too)
