4.2 Comments
Comments are purely for information and explanation purposes. They act in
the same way as
REM
commands by not acting on the program.
Comments begin with a double forward slash [//] or a semi-colon [;]. They
can be placed on their own line, or at the end of instruction lines. A
Comment ends at the end of the line.
Example
//This line contains a comment, which ends with the line.
//If the comment flows onto the next line, double forward
//slashes must be used to start the next line.
