 | [chars2.bf](chars2.bf)     |         | ???                 | ?/?/9?   | Modified version of chars.bf that was distributed as chars.bf for the longest time. Outputs all chars on 1 line. Program is 3 rows tall instead of 2. Unclear who made these modifications, or why.
 | [chars3.bf](chars3.bf)     |         | Chris Pressey       | 5/29/118 | Modified version of chars2.bf that does not use stringmode and thus can be compiled by bef2c.

 | [ea.bf](ea.bf)             | CC0     | Chris Pressey       | 9/5/93   | Makes 'enigmatic aphorisms.' A loose interpretation of a program in '1001 things to do with your Commodore 64.' This is an example of how to simulate a 'gosub' with a value.

(Users should be warned that the significance of the output of this program is of extremely questionable practical value. But it is consistant.) (This algorithm is also known as the "digital root".)

 | [pangram.bf](pangram.bf)   | CC0     | Chris Pressey       | 8/25/112 | Checks if the first line of input is a pangram -- a sentence which contains all the letters of the alphabet, such as "The quick brown fox jumps over the lazy dog" or "Pack my lunch box with five dozen liquor jugs." Case-insensitive, and ignores most punctuation, but "high" punctuation (above ASCII character 90) will likely confuse it.
