Run by Gunnar Kanold since 2011, you can submit game or programs written for any BASIC for 8-bit home computer for which an emulator is available. Some of the entries in previous years were astounding, and give an example of the abilities of classic computers like the the Commodore 64 or Atari 800. text/html 2025-12-13T12:33:10+00:00 Anonymous (anonymous@undisclosed.example.com) https://retroprogramming.iwashere.eu/ugbasic:datatypes?rev=1765625590&do=diff ugBASIC User Manual Data Types ugBASIC offers many built-in data types, some primitives and some complex.
