Hi,

I'm having problems figuring out how to select and set digits within numbers.

For example, I want the user to enter a number:

"Enter Number" ? -> A
(Int log A)+1 -> B

Above would be the start of the program. After this, I would like a line that selects, let's say the 4th digit in the number A and sets its value as C.

How can this be done?

----------

To clarify what I mean:

"Enter Number" ? -> A

<-- User enters number, e.g 442

(Int log A)+1 -> B

<-- This responds as how many integer digits the number has, in our case for 442, 3.
After this I want the second digit in 442 to be selected and set as C.

Hope you can help. Thank You.

Alf. <:3D~

You'll want to split the number just above and below the digit you want to replace, then multiply C by the place valuse of the digit, and add the remaining vars togather. The biggest problem would be the splitting. For the upper numbers, you could devide them so that only the numbers that are to the left of the digit you want to replace are to the left of the decimal; you could then get the number part of that. A similar strategy could be aplied to the numbers belw the decimal. Be aware that this will all fail if you try to replace a digit with a to-digit number.

Does this work?:

StrMid(Str 1, 2, 1) -> Str 2

String 1, 2nd Char, 1 char long (I think)
(Sorry, I'm not very good at string stuff)
