in reply to Add part of one hash to another

If you just want to omit that field, you could read File B like this:

while ( <TEXTFILE> ) { $csv->parse($_); push @H_USES, [ ($csv->fields)[0, 2..10] ]; # or whatever the numb +er of fields in the file }
Looks a bit simple ... have I understood the problem correctly? :)

    Hi - I need the complete data from File B for other things later in the program, but both of the responses provided me with valuable examples and I appreciate all the help!
      I need the complete data from File B for other things later in the program
      Here is another way which may help:
      # reading data in from File A while ( <> ) { $csv->parse($_); push(@AoA, [$csv->fields]); } # reading data in from File B while ( <TEXTFILE> ) { $csv->parse($_); my @fields = $csv->fields; push(@H_USES, [@fields]); # Make a copy of the fields my @array = @fields; # Make the new array same format as File A splice(@array,2,1); # Remove Field 2 for example # Push the new array onto $AoA from File A push(@AoA, [@array]); } close(TEXTFILE); print "Done Loading USES Data\n"; # load up the hash $HoA for my $i ( 0 .. $#AoA ) { $HoA{$AoA[$i][5]} = $AoA[$i]; } # end looping over rows # load up the hash $H_USES for my $i ( 0 .. $#H_USES ) { $H_USES{$H_USES[$i][5]} = $H_USES[$i]; } # end looping over rows
