These are some simple examples of the BASIC programming language written for the Tandy Color Computer 3. However, all of the text programs should work in any BASIC interpreter!
I made these as a docent at the Isett Heritage Museum in Huntingdon, PA as quick programs guests could enter to try out the CoCo 3 while on a tour!
01: HELLO WORLD
Everyone's first program!
Simply prints HELLO, WORLD! to screen.
02: HELLO WORLD INFINITE LOOP
Using a GOTO line, this program infinitely prints out HELLO, WORLD! to screen.
Tip: If using a Color COmputer 3, press the [ESC] key to terminate the program.
03: HELLO WORLD FOR LOOP
Using a FOR loop, this program prints out HELLO, WORLD! to screen ten times.
04: TEXT INPUT WELCOME
Using the INPUT function, this program welcomes the user to the field of programming by name!
05: MULTIPLICATION TABLES
This program creates a game to practice multiplication tables.
It introduces concepts like if/them statements, math operators, and integer inputs.
06: NUMBER GUESSING GAME
This program expands on the concepts learned in the previous program to create a number guessing game!
07: MAD LIB
Using text inputs, this program creates a playable mad lib!
08: EXACT AGE CALCULATOR
This is the most advanced of these sample programs.
This program creates a calculator that finds your exact age down to the day! It accounts for leap years.
09: GRAPHICS - RANDOM LINES
This is the first of the programs to run exclusively on the Tandy Color Computer 3.
Using the graphics functions exclusive to this machine, the user creates a program that generates lines of random length and direction in random colors.
10: GRAPHICS: ETCH-A-SKETCH
Like the previous graphic program, this code only can run on the Tandy Color Computer 3.
Using the graphics functions, this program creates an Etch-A-Sketch that draws using the cursor keys!
