How to write comment in SAS code

Comment is very helpful and recommended for programmers to use because it helps if other than original developer needs to update the code. There are two ways to comment in SAS programming. You can use either one.

1. Start with * (asterisk) and end with ; (semi colon).

This way you can comment only one line. You can write anything in this place. Example: *This is comment;

2. Start with /* and end with */.
   
   Shortcut - CTRL+/ to comment, CTRL+SHIFT+/ to uncomment.

This way you can comment any number of lines. All the texts inside these two signs will not be used in SAS run. Example: /* This is SAS comment. */
