If I were doing it, I would consider parsing the command using TSO/E Parsing services. But if you're going to do it by yourself, you see if there's an opening ( or not. And, actually, it's possible that the command format you get will always have the parentheses, even if there's only 1 ID in the list. But if there's a ( then you find the first non-blank after it, and then look for the next blank or ), and that's your first ID. You keep going until you've accumulated all of them, and you're done when you get the ) that ends that operand. I don't understand what you mean (in the part I didn't quote) by "the length is bugging you". You know the length of the buffer. (And it won't always be 248, it could be much longer (probably up to 32768 or so).) You keep going until you hit the ) or until you hit the maximum number of user IDs you've programmed your code to handle. If you hit your maximum limit, you either lose data, or if that's not acceptable to you and your customers you abort the command. -- Walt
