Hi everyone I am thinking of creating our own product codes in the form of 2 letters and 2 numbers but they need to be 8 chars in length, I know I will need to loop through but am unsure of how to start it. Currently we use, for example January a,b,1,2 so we would want eg, aa12ab22 OR 1a2bb1a2 No character should repeat four times aaaa isn't acceptable. How can I setup my script to produce ALL permutations of the above in one run? Hope that's clear enough for someone to point me i
