REM Statement Details
 
Syntax
  REM remark
  ' remark
 
REM statements are not compiled, but they appear exactly as entered when
the program is listed.
 
You may branch from a GOTO or GOSUB statement to a REM statement.
Execution continues with the first executable statement after the
REM statement.
 
A single quotation mark can be used instead of the REM keyword.
 
If the REM keyword follows other statements on a line, it must be separated
from the statements by a colon.
 
REM statements are also used to introduce metacommands.
 
  Note: Do not use the single quotation form of the REM statement
        in a DATA statement because it will be considered valid data.
