Hello all. For reference: 

column relationship value filter_or_append order
a      <=           0.3   filter           1
b      ==           abc   append           2
c      <=           0.3   filter           3

My program reads in this filter file and stores each value in an array. 

        if (eval "$hash{$filter[0]->[0]} $filter[0]->[1] $filter[0]->[
+2]")
        {
            if (eval $hash{$filter[1]->[0]} $filter[1]->[1] $filter[1]
+->[2])
            {
                if (eval "$hash{$filter[2]->[0]} $filter[2]->[1] $filt
+er[2]->[2]")
                {
                    print OUTFILE $line, "\n";
                }    
            }
        }

Whats going on: If the hash of column a evaluates to less than or equal to the value specified in the filter file (.03), continue. This part works. Then, if the hash of column b evaluates to 'equal' (== or eq; I have tried both meaning I have changed the values for column b in the filter file to both '==' and 'eq' and tried to run the program that way but no luck) the value specified in the filter file (abc), continue. This part does not work - Any comparison/evaluations of numerical values works and I can print the results to an output file. However, when I try to do this same comparison/evaluation with strings, wrong output (if any) is printed to the output file. What is a solution to compare/evaluate a string with the code I have already written?

Thank you!
