How do I change symbol #4 to 0?

=> str = (99909)

thx.

You can use tokenat to get each letter.

Then insert each one into a temporary string.

When the letter index is equal 4, you will insert 0.

After that, you set your string equal temporary string.

I thought there is an automatized command, but, anyway, thank you :)

If someone else will read that topic, here is my way to solve the problem:

My solution:

with index=4, newCharacter="0", string= string to change.

system | set string to left(string,index-1)&newCharacter&right(string,len(String)-index)
