* Stata Comments   *
********************

//Three ways to write comments in stata

/*
1. Double Forward Slash
2. Asterisk
3. Forward Slash and Asterisk	
*/

//1. Double Forward Slash

//can be used at the begining of line or a the end of line
//any thing appearing after double forward slashes will not be executed as command
sysuse auto,clear //This command will load auto dataset
sysuse auto //,clear //Now clear option will not be executed

//Must have a space between command and forward slashes
sysuse auto,clear//Wrong way of doing it.


*2. Asterisk

*A single asterisk at the begining of a line will turn the line to a comments
*can only be used at the begning of line not at the end of in the middle
*can be used intereactively 
*sysuse auto,clear
sysuse auto,clear *this asterisk sign wont work


/*3. Forward slash and asterisk

Any thing between "/*" and "*/" will be considered comments

sysuse auto,clear

The above command will not be executed 
*/

sysuse auto /*,clear
like double forward slashes in can be used at begining, middle or end of line.
Usually they are used to comment out long line of code or comments
*/


sysuse auto /*middle*/,clear
