  Key Concepts: 
  The match function is a component of the BC-ABA ABAP Runtime Environment. It is used to compare two strings and determine if they are equal or not. The match function can be used to compare strings of different lengths, and it is case-sensitive. 
  
  How to use it: 
  The match function is used in ABAP programs to compare two strings. The syntax for the match function is MATCH(string1, string2). The function will return a value of 0 if the strings are equal, and a value of 1 if the strings are not equal. 
  
  Tips & Tricks: 
  When using the match function, it is important to remember that it is case-sensitive. This means that if you are comparing two strings that contain capital letters, they must be identical in order for the match function to return a value of 0.
