===== REM  =====

===== SYNTAX =====
     REM [comment]
     ' [comment]

==== PURPOSE ====


In BASIC, the ''REM'' keyword (also abbreviated by the single quotation character (')) 
is used to insert comments into code. A comment is a note or explanation that is added 
to code to make it easier for the developer to understand, as well as for other
programmers who may read it in the future. 

When the computer compile the ugBASIC program, it completely ignores everything that follows 
the ''REM'' keyword on the same line. The word ''REM'' can be placed at the beginning of a line
or after a colon. In either case, the rest of the line will be treated as a comment.
To comment out multiple lines of code, you can use ''REM'' at the beginning of each line.
Note that you cannot continue a ''REM'' statement by using a line-continuation sequence 
(''_''). This means that, for a multiple-line comment, you need to use as many ''REM''s
statements as the lines you comment.

Comments have the role to describe the purpose of a particular section of code 
or individual statement, and it provide information about the program, who created it, 
when it was created, and what changes were made. They make code easier to understand, 
even for people who didn write the program: when you return to code after some time, 
comments help you remember the purpose of different parts of the program.

Moreover, it is the best way to disable
a piece of code without deleting it, simply add ''REM'' to the beginning of the line.

The main guidelines in using ''REM'' it to use simple, direct language to explain the code,
avoiding long or complicated sentences. Generally, they should be used on parts of the code 
that are not obvious. You do not need to comment on every single line.
