REM Instruction

REM

Followed by a comment on the same line. This comment is copied to the results file ('.res'). A line beginning with at least one blank may also be used as a comment, but such comments are only copied to the .res file if the line is completely blank; REM comments are always copied. Comments may also be included on the same line as any instruction following the character '!', and are copied to the .res file (except in the case of atoms and FVAR, EXTI, SWAT and BASF instructions).
