10 What the DISK BASIC is The DISK BASIC has a strong file control function relative to the cassette base . BASIC. For example, it makes

11 • Data file control There are two types of data files, depending upon the format of file access (the method of data read-out and write-in). One i

12 • Program file control The BASIC program file control commands CHAIN (page 44) and SWAP (page 45) are for read-out of another program in

Section 1 DISK BASIC OUTLINE This section explains the features of the DISK BASIC and outlines the file controls. First of all is an explana
