Hello,
I have two strings as follows:
String abc ="123456789"; //this string always hold numbers
String def; //this one will be converted later to INT
and would like to extract the 1'st 5 characters from string abc and put it in string def for further processing.
So, substring is out of the question because there is no special character I can use for a reference. And can't find a suitable command to do it.
Any help is appreciated.
This will be helpful to you:
Of course you should just use char arrays instead, which can be manipulated in the same way:

Why is substring out of the question?

It is not a good idea to use the String (capital S) class on an Arduino as it can cause memory corruption in the small memory on an Arduino. Just use cstrings - char arrays terminated with 0.

Array did it for me.
Thanks Pert and all.
