Comment by making a REMark using the REM keyword

<lang qbasic>REM COMMENT AFTER THE REM KEYWORD</lang>

When LISTing the program a space is added after the REM keyword

<lang qbasic>0 REMLEAVE THE SPACE OUT AFTER THE REM WHEN TYPING OR PASTING</lang>

The remark extends until the end of the line. Only the first THIS IS CODE is printed.

<lang qbasic>10 PRINT "THIS IS CODE" : REM : PRINT "THIS IS CODE"</lang>

A comment can come after a GOSUB and when the subroutine returns it continues running the statements after the GOSUB comment.

<lang qbasic>20 GOSUB 110COMMENT: PRINT "THIS IS CODE"</lang>

Anything after a GOTO or RETURN statement is ignored.

<lang qbasic>30 GOTO 40"COMMENT: THIS IS A COMMENT</lang>

There are other ways to add spacing and comments to code.

<lang qbasic>::::::::::::::::::::::::::::::::::::::

40 REM

50 :

60 REM<ctrl>+J

70 FOR I = 1 to 10

80 ::::PRINT I;MID$("THIS IS A COMMENT",1,0)

90 NEXT</lang>

Typing CONTinue after the program ENDs will result in a ?SYNTAX ERROR.

<lang qbasic>100 END : THISISACOMMENT</lang>

Use the quotation symbol " before the comment so that spaces are included and keywords are ignored.

<lang qbasic>110 RETURN : "COMMENT FOR AND AT THE END</lang>
