Function Syntax

The function syntax is fairly simple. The basic form of a function is: 


    123456 1234 

 		 function  (  argument list  ) 


 		 {               


local  ( local variable list  ) 


 		 		               


 		 		 statements    


 		 		               


return expression  


 		 }
The local, and return statements are optional. If a syntax error is encountered while the function is being entered (read), definition of the function must begin again, from the very beginning.
