Comments

ABAP has 2 ways of defining text as a comment:

• An asterisk (*) in the leftmost column of a line makes the entire line a comment
• A double quotation mark (") anywhere on a line makes the rest of that line a comment

1. Line Comment: If you want to comment whole line, you can put * sign in front of the line.
   Example:
   

   * Comment Line
   WRITE: This is the example for commenting. 

2. Partial Line Comment: If you want to comment partail of line, you can put " sign in front of the comment text
   Example:
   

   WRITE: This is the example for commenting.    "Comment Line

Example:
