Multi-statements: You can describe multiple statements in one program line by separating
them with a colon (:).
[ 3 ] Comments
A single quotation mark (’) or REM can begin a comment.
• Single quotation mark (')
A single quotation mark or apostrophe (’) can begin in the first column of a program line
to describe a comment.
When following any other statement, a comment starting with a single quotation mark
requires no preceding colon (:) as a delimiter.

PRINT "abc" ’comment
• REM
The REM cannot begin in the first column of a program line.
When following any other statement, a comment starting with a
REM requires a preced-
ing colon (:).
