SAS Comments

Two Types of Syntax

Type comments in between /* and */

/* Create the HHTYPE Variable */
Type comments in between an asterisk and semi-colon

* I'll select these folks later..... if HHTYPE="Old" ;

NOTE: The forward slash asterisk commenting style can span comments made by asterisk semi-colon:

/* I don't want to run this code ******
* I'll select these folks later..... if HHTYPE="Old" ;
       proc print data=households;
       run;
