I also normally use "do" to create incremented container names. It now seems that you can do the same thing with "value" in a repeat loop. Not certain -- I'm pondering. Are there things you can do with "do" that you can't do with "value"? Maybe, in some cases, "do" would produce a more concise script. The trouble with "do" is that I usually make mistakes with the quote constant, the & and && operators, spaces and quotation marks. After the "do" command is done evaluating, I end up with too many quotes and spaces or too few, or in the wrong places. Then I have to fuss with it until I get it right. If my "do" statement is complex, I'll usually assemble a "do" statement in a variable. Then "answer myDoVar" When it looks right, I'll change it to "do myDoVar" That helps, but it's still a hassle.
