Hi,

I am trying to use tr to do a binned replacement of a bunch of characters ASCII 33-126 where I bin the replacements as 33-42, 43-52, 53-62 and >62 and rename them 0, 1, 2, and 3.

I have tried all combinations (but not the right one) to affect this and seem to get at best replacement of all values to 3. Here are a few iterations: 

###$quality =~ tr /[!"#$%&'()*][+,-./01234][56789:;<=>][?@ABCDEFGHIJKL
+MNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~]/0123/;
            ###$quality =~ tr /[\!-\*][\+-4][5-\>][\?-\~]/0123/;
            ###$quality =~ tr/[\x21-\x2a][\x2b-4][5-\x3e][\x3f-\x78]/0
+123/;
            ###$quality =~ tr/[\x21-\x2a][\x2b-\x34][\x35-\x3e][\x3f-\
+x78]/0123/;
            ###$quality =~ tr/[\!-\*][\+-4][5-\>][\?-\~]/0123/;

Any suggestions?

Thanks,
