This command has no purpose when a program is RUNing. It is however used to place comments in the program which can be useful when you later come to edit a SuperBASIC program. Anything which appears after REMark on the same line, will be ignored by the interpreter, thus allowing you to make any sort of comment you like.
100 REMark Line 110 could be altered to: 101 REMark 110 INPUT ‘Your name’;a$:IF password$<>a$:STOP 110 Name$=’Author’
Another means of splitting a SuperBASIC program into sections is to include program lines which only contain a colon (:), for example:
100 PRINT "End of Program":STOP 110 : 200 DATA 'Some data to read'
