The Rem command is another way of specifying a full-line comment in code, used for compatibility with traditional BASIC. The rest of the comment line must consist of legal text characters and cannot have unbalanced quotation marks (because the comment still passes through the tokenizer). No other syntax checking is performed.
Syntax

Example
