Alphaprint is a language made by User:PythonshellDebugwindow.
The program is made up of an arbitrary-size repeating lowercase string of the alphabet, e.g.
abcdefg would be a valid program but
zyxwvut wouldn't be.
Any uppercase character will output the ASCII character of its position in the code modulo 256. For example,
would output the 33rd ASCII character (
!) because the capital 'G' is the 33rd position in the source code.
