BASIC Week 2: Halloween Boogaloo http://reddit.com/r/RetroBattlestations
In here you will find the BASIC program for a contest used on http://reddit.com/r/RetroBattlestations. The program was intended to be reusable and reasonably portable to many different BASIC flavors. The "graphics" are character based and have some simple sprites. It should be portable to any BASIC that has the ability to position the cursor at a specific location. Don't have a retro computer and don't want to figure out how to setup an emulator? Try the Apple II version in your browser: http://retrobattlestations.com/AppleII/HalloweenBoogaloo.shtml === Typing Tips === When typing the program in you can leave off any lines which contain REM, they are not needed for the program to run. You can also leave out all whitespace. Note: On the TRS-80 Color Computer and BBC Micro you need to include the spaces around any IF, AND, OR, or THEN statement. If you make a mistake and don't want to retype the entire line, most of the BASICs have a way to make corrections. Apple II computers: On an Apple II+ use LIST <line number> to print the line with an error, then use ESC followed by A/B/C/D to move the cursor one step at a time. Position the cursor at the beginning of the line, then use the right arrow to move over the line and fix the error. Be sure to arrow all the way to the end of the entire line before you hit RETURN! On an enhanced Apple IIe, Apple IIc, or Apple IIgs you can also use ESC with the arrow keys. In 80 column mode (enter with PR#3) the cursor will change to a white block with a + in it, push ESC to drop out of movement mode. BBC Micro: Use LIST <line number> to print the line with a mistake, then use the arrow keys to move up to the beginning of the line. Each press of the copy key will type in the character under the cursor. Make any necessary edits by just typing on the keyboard and using copy to avoid retyping everything. Commodore 64 and Plus/4: Like the others, use LIST <line number> to display the line with problems, then use the arrow keys to move up and make any corrections. By pressing shift-INST you can insert a blank character if you missed something. Unlike the Apple II you don't need to arrow to the end of the line before pushing RETURN. TRS-80 model 100: This has to be the best built-in BASIC editor I've seen so far! Just type EDIT and the entire BASIC program will be loaded into the built-in word processor where you can make any changes you want. Press F8 to exit the editor and go back to BASIC.
