Add 1 to the value returned by index.

Could you please explain the full line ...what happens when 1 is added to the value returned by index???????/

so that position becomes the starting point for the substring instead of the usual "first position"?

In this example:

00000000-11111111

the index returns a value of 9(hyphen is in the 9th position)

so +1 means "we are telling the substr function to take the values from 10th position????is that right?

aND FROM THERE WE ARE TAKING 9 CHARECTERS???/

Hi Robertrao,

Yes, it is right.The index function returns a value of 9, so the substr function take the values from 10th position.
