AmigaBASIC Inside and Out from Abacus, a Data Becker Book, 1988. Softcover, measures approximately 7" x 9.5". Pre-owned in good condition. There's wear to the covers, including a small tear on the front cover (as shown close up in pic #2). Some of the pages have creased corners. There is a name written on one of the front pages, but I didn't find any writing on the other pages.
