How can I use a collection of nested for loops (or any other type) to produce a sequence like this with these variables:

length is how many digts to go to
max is the maximum number
min is the minimum number

Lets say for this case:

length = 2
max = 3
min = 1

it would produce:

11
12
13
21
22
23
31
32
33

This works "ok" for only length = 1, but not really, since I still have annoying 0's at the start 

For i = 1 To length
For ii = 0 To i
For iii = 1 To 5
Console.WriteLine(Str(ii) + Str(iii))
Next
Next
Next

    Yep, the console window :) I was just wondering if there was a possible algorithm for it. Also, sorry for syntax issues and formatting and such. Still a noob at this website xD Commented Jul 12, 2013 at 18:48

As this looks like a homework problem, I am going to attempt to help you think through this problem without actually giving you the answer in code.

Let's think through this problem...

You have the range 1-3. So your first sequence is easy:

1, 2, 3

Now you want to produce a sequence from 11 to 13. What's the change, or difference, between 1 through 3 and 11 through 13? The answer is you've added 10.

The same is true for 21 through 23 - you've added 10 again.

So, what you want to do is iterate from 1 through 3.
Then, iterate from 1 through 3 this time adding 10.
Then, iterate from 1 through 3 this time adding 20.

Thinking about this, you are essentially doing this:

1
2
3
10 + 1
10 + 2
10 + 3
10 + 10 + 1
10 + 10 + 2
10 + 10 + 3
etc

Or, you could also think about it like this:

(0 * 10) + 1
(0 * 10) + 2
(0 * 10) + 3
(1 * 10) + 1
(1 * 10) + 2
(1 * 10) + 3
(2 * 10) + 1
(2 * 10) + 2
(2 * 10) + 3
etc

Can you see a pattern forming?

I.. can :'D This isnt a homework problem as such. What im trying to do is have min and max as 32 and 126, then transfer these to characters based on their ASCII codes. So it goes: aa ab ac...
@TonyCantone - OK. We do get homework problems on here every now and then, so we try to help students rather than help them cheat. :)
@TonyCantone - Working with Excel, perhaps?
:) Your code works well. Now can/will I use the same method for length = 3? So after 33 it will go 111, 112, 113, 121... When I say "the same method" I mean writing the numbers out and thinking logically about it :P
Ah, wait. Ive just thought of something. Ive been going about this all wrong facepalm. Ive actually just discovered that I just need the possibilities for the given length. So length = 1 would produce 1,2,3. length = 2 would produce 11,12,13,21... Thus the singe characters are not needed
