[PD] Pd *is* a programming language!

Hi everybody,

Remember those long discussions about whether Pd is a programming 
language or (an inferior) something else?

Well, to settle the matter, I made a brainf*ck[1] interpreter in vanilla 
Pd using no externals[2].

Now you can be sure that you can compute anything computable[3] using 
your favourite multimedia tool!

As Pd's string handling sucks, output is a printout of the decimal value 
of each character.

Keyboard input is through [key], so you enter characters fairly 
naturally (wait for the yellow signal before you type each character). 
There is no way to indicate end-of-file.

[2] As Pd's string handling sucks, you need to convert your .bf source 
code into decimal form before loading it.  A simple C program 
"decdump.c" to do this is attached.

[3] Provided it can be computed within the memory available, which in 
this interpreter is 1,000,000 cells each being an integer from 0 to 255 
inclusive.
