Automation Blocks - String to Number, Version Up

[m1jackson]

I get why in the following example when adding "003" + 1 = 0031 because it's a string concatinating with a number. So adding a number with a number gets the proper result of "4".

My question is two parts:

1. How would I extract out the padded number "001" from a filename string to treat it as a number.
2. Version up that number and pad it back to 3 numbers before adding it back into my file name?

INC_301_501_ptv_v001.aep

INC_301_501_ptv_v002.aep

I can't leave it as just v1, v2, v10 as clients make it a requirement for sorting purposes.

For the first part of the question: the "round" block in the math category can for example be used to convert a text to a number. This sample code first alerts "4" and then "5":

To get this back into a 0 padded string you need to check its length with the "length of" block and add 0 as necessary.

Here is the detailed answer to your second question (extending a number like "12" to 0012.

Attached you find a function which does exactly that. The example here will alert "0012"

Also note that this function works no matter if the argument "number" is a number or a text. But it won't trancate the numbers. So if you try to bring 99999 to a length of 3 it will return the 99999 unchanged.

As always, your is a far superior solution. Just so you know, I really am trying to figure this stuff out and this is what I had come up with before you posted your second reply.
