substring()

Purpose

substring(str, start, subStringLength)

Creates a substring from str. The substring begins at start and is at most subStringLength characters long.

Note

The first character of the string has the value 0. So if you set start to ‘2’, the substring will start with the third character.

Example

In the following example a substring from the string is created, starting with the 4th character and being 5 characters long.

substring("123456789", 3, 5)

This example will result in the substring “45678”.
