Is there any way I can have a variable number of nested For ... Next loops?
In other words, I want x loops. If x=2 there would be 2 loops, if x=3, 3 loops. This is a follow-up to a question I posted May 29 about all permutations. The answer I got was helpful and gave me ideas but didn't actually solve my problem. I realize what I really need to figure out is the variable number of loops. Thanks for any help. |

you need to read up on RECURSION
it sounds like what you really need is a recursive function ... ie one that calls itself. an example would be when finding all the files in a folder ... the function created to find files would call itself if for any subfolders. Another example would be for factorial numbers eg 5! is the same as 5x4! which is 5x5x3! ... "KAH" wrote in message ... Is there any way I can have a variable number of nested For ... Next loops?

You can't create nested loops "on the fly", but maybe a solution like this
would work for you. Set up all the nested loops you will possibly need and check whether that level should be run or not in its first statement and, if not, exit the loop before it does anything (this will short circuit and further nested loops right then and there). Here is an example structure for you to consider (I set it up for 4 nested loops, but the concept can be carried on as needed)... NumberOfLoops = 2 For A = # To # ' ' Code for the "A" loop ' For B = # To # If NumberOfLoops = 1 Then Exit For ' ' Code for the "B" loop ' For C = # To # If NumberOfLoops = 2 Then Exit For ' ' Code for the "C" loop ' For D = # To # If NumberOfLoops = 3 Then Exit For ' ' Code for the "D" loop ' Next Next Next Next -- Rick (MVP - Excel) "KAH" wrote in message ...

Thanks to everyone for their rapid responses. This idea of exiting loops
works best for my program and is simple. Thanks! "Rick Rothstein" wrote: You can't create nested loops "on the fly", but maybe a solution like this would work for you.
