REM Statement

Purpose:

To allow explanatory remarks to be inserted in a program.

Syntax:

REM[comment]
'[comment]

Comments:

REM statements are not executed, but are output exactly as entered when the program is listed.

Once a REM or its abbreviation, an apostrophe ('), is encountered, the program ignores everything else until the next line number or program end is encountered.

REM statements may be branched into from a GOTO or GOSUB statement, and execution continues with the first executable statement after the REM statement. However, the program runs faster if the branch is made to the first statement.

Remarks may be added to the end of a line by preceding the remark with an apostrophe (') instead of REM.


Note

Do not use REM in a DATA statement because it will be considered to be legal data.


Examples:

.

120 REM CALCULATE AVERAGE VELOCITY
130 FOR I=1 TO 20
440 SUM=SUM+V(I)
450 NEXT I
