comments

comments in the source code begin with the sequence '//' and end at the end of the line

e.g.

// this is a comment

a = b + 1     // this is another comment

// this is a long multi
// line comment spread
// over three lines
 
 
 

a = b + 1	// this is another long
c = a * 2	// multi line comment spread
	// over three lines
