PROGRAMMING CONCEPTS has been a multi-part feature in TIME DESIGNS, and deals with programming on the Sinclair ZX81 (or TS1000/TS1500). The chief example used in this series is a game program called “ZX81 TIC-TAC-TOE” which has been discussed extensively. In this installment we feature the actual BASIC listing of the program.
If readers do not wish to type in the listing, there is a cassette tape available (non-listable) for $12 from the author: Albert F. Rodriguez, 1605 Pennsylvania Ave., #204, Miami Beach, FL 33139. Also, you can get a print-out of this listing along with the array content and program declarations for $6.20 ppd (foreign buyers add $2.00 for the cassette, or $1.00 for the listing).
In the next issue, we will have a complete line explanation of the program and more.
