> I want to insert a lowercase letter as the fourth character in a list of filenames. I thought I put the right string in, but it just gives me the same letter (in this case 'a') over and over again. I want the letter to increase by one for each file. So track 2 should have a 'b', track 3 a 'c', ect. This is what I used: A1.$char($add($num(%1,1),97)) %2 The lowercase letter comes after A1. The 97 indicates the lowercase 'a', but what am I not doing right to get that letter to increase for ea…

If you show us some real examples, this would help to make suggestions.
