When looking for a match in a pattern I always used the grep function, however using this function has the limitation that it does not look for an exact match but rather for a pattern match. If I look for ACB and I have in my array ACBD it will match it while I don't want it to be matched. Anybody has a good idea on this without changhing to much of the routine as I like it that short. 

    if (not grep($_ eq $machine_sheetname,@sheets))
        {
            push @sheets,$machine_sheetname;
            $skip = 0;
        }
