Super Startrek
The startrek program is one of the games in the famous BASIC Computer Games published in 1978. In the book it is called 'Super Startrek' and the code is available in Vintage BASIC. Here it is with a few modifications to match the 40 column display of the Thomson MO5.
Use of non-standard procedures and functions:
- CLS -- Clear screen
- CLEAR 600 -- Reserves 600 bytes of memory for strings and clears the space
- INKEY$ -- Checks the keyboard and returns the key being pressed
- DEFINT -- Defines variables as integers
MO5 BASIC 1.0
Empty lines added for clarity.
