Drew, could it have been done in a recursive fashion, better than the "spaghetti Code" Max Ps. I love this song....be my soldier boy....1962 top hits.

Ummmm, no. What I am describing is a jump point. Not a loop. A loop does something over and over. A jump point is when something needs to be 'looped' but conditionally on many factors. The example I initially gave, could have been put into a function, that was called in a loop, but to handle the 'skip everything if this or that didn't happen', you would either need to put a lot more logical conditions in, or put in an Exit function, which would mean you are leaving a function at multiple points....OR, a Goto EndOfFunction where you would go to the end of the function. OR you can put a starting point, and if all the conditions run through, it's fine, if any one of them fail, it can return it to the start. When you exit a loop (due to a condition), the code LEAVES the Do Loop. Yes, you could nest one loop inside another, but it just simply does not give you the abilities that a Goto statement has. If you wanted to be able to return to three unique steps in a process, nesting the loops would be crazy. The point is, Goto's can be a big factor in 'spaghetti' code, but they can also make your code cleaner, and more logical.

True, but why would you construct it that way? You're essentially describing a callback. And you CAN nest Do Loops, even in VBA.

Why? Code is used to make a functional project. It's primary purpose is to do just that. After that, the code should be organized and readable, and as optimized as possible. With proper objects and function, this can be accomplished. With the exception of errorhandling a goto statement is going to be a rare case, but NOT an excluded case, to make the code readable and organized. In my example, making a do loop would require addition logic on each step, because when you exit a loop, it starts all over. A Do Loop cannot have extra 'loop' statements. Ie: Do 'some condition is met: then Loop Loop Can't do that. You can do that with a Goto statement.
