• Key Concepts: 
  Offset/length specification is a feature of the ABAP Runtime Environment (BC-ABA) that allows users to define the start and end points of a string or data object. This is useful for extracting specific parts of a string or data object, such as a substring or a specific field. 
  
  How to use it: 
  Offset/length specification can be used in ABAP programs by using the READ statement. The syntax for the READ statement is READ  [OFFSET ] [LENGTH ]. The offset is the starting point of the string or data object, and the length is the number of characters or bytes to be read. 
  
  Tips & Tricks: 
  When using offset/length specification, it is important to remember that the offset starts at 0, not 1. This means that if you want to read the first character of a string, you should specify an offset of 0.
