Instruct the compiler that comment will follow.
REM or '
You can and should comment your program for clarity and your later sanity.
You can use REM or ' followed by your comment.
All statements after REM or ' are treated as comments so you cannot use statements on the same line after a REM statement.
Block comments can be used too:
'( start block comment
print "This will not be compiled
') end block comment
Rem TEST.BAS version 1.00
Print A ' " this is comment : PRINT " Hello "
^ - - - This Will Not Be Executed!
