Commodore BASIC is the dialect of BASIC used in Commodore International's 8-bit home computer line, stretching from the PET of 1977 to the C128 of 1985. The core part was based on 6502 Microsoft BASIC, licensed from the young Microsoft on a "pay once, no royalties" basis.
A very convenient feature of Commodore's ROM-resident BASIC interpreter and KERNAL was the brilliantly implemented full screen editor, which allowed users to input, edit, and enter direct commands as well as program lines anywhere on the screen – simply by pressing the
RETURN key whenever the cursor happened to be on a line containing a valid BASIC statement. This marked a huge leap forward in program entry interfaces compared to other common home computer BASICs at the time, which typically used a separate
EDIT command for line editing.
