Specifies that a program line is a comment.
Text: Any text that serves as a comment.
You can use the single quotation mark instead of the Rem keyword to indicate that the text on a line is comments. This symbol can be inserted directly to the right of the program code, followed by a comment.
You can use a space followed by the underline character _ as the last two characters of a line to continue the logical line on the next line. To continue comment lines, you must enter "Option Compatible" in the same Basic module.
