As far as I have ever seen these control numbers are used by the translator to note which ST/SE it is translating. So within the GS/GE each ST/SE control number is unique. I don't recall that they have to be in any particular order or that they have to be consecutive; however, most of the time they are generated in numeric order.

Also, just because a field is alphanumeric it does not mean that only alpha or only numeric characters must be used, it simply means that both are allowed. Therefore, a string of numbers only is just as valid as a string of alpha characters or a string of both. Since the purpose of the ST control number (in my opinion) is to indicate position in the GS as well as "count" them, numeric makes the most sense to my human brain. Alpha would work ok up to 26, but then one would either need to start adding numbers or AA, AB, AC or would it be AA, BA, CA? And, would AA come after Z or would my translator somehow put AA after A and then B? You see the point here, once you get outside the "box" of straight numbering, there are too many variables for easy integration. Having said this, I don't know any translator that would automatically check for sequence in ST control numbers and a person could figure it out, as this would likely only be done in the case of an error. In that case, why make it harder on your TP? Pretty much everyone uses Arabic numbers and can count, if they're in this business. I have seen trading partners use a numeric format of the ISA or GS control number followed by 0001, 0002, etc as the ST/SE control numbers and I have seen other numeric permutations used. I've also seen alpha characters in GS control numbers, but not yet in ST/SE. Unless you count spaces, which you should, as they're technically "alpha". IMHO any decent translator should be able to deal with ST*856* 1' for example and not require ST*856*0001', although I have run into issues with that before, as well.
