Hello Monks

I need help on an perl warning. I am looking at the code for hours but I can't figure out the problem

Perl is complaining about the useless use of a private variable in void context on line 157 (#2) (W void)

Here the code:
Its a sub for parsing the content of a map-file.
Line number 157 is marked by a comment.

Any help is welcome!!!

sub ProcessMapFile { my $self = shift; my $MapFile = $_[0]; my $PlaceToPutInformation = $_[1]; #Each config profile defines its own way how to parse the map-file +. my $iterator = $ProfileInformation->{'StartLine'}; #Process map-file for ( $iterator ; $iterator < @$MapFile ; $iterator++ ) { if ( $MapFile->[$iterator] =~ m! ^ #Begin with..
