I remember QBasic was notably different from Applesoft Basic in that QBasic did not require line numbers, and one of the demo programs (remline.bas) removed line numbers for you. Of the variants used by this author, the Commodore Basic variant is distinct in being the only one with line numbers. The others all look very similar.
