It is a program that I wrote in Pascal and compiled to executable. When 
I do and IDENT it says
Size            #428
CRC           GOOD
Parity           $85
Exec Off       #25
Data Size       #1058
Edition           #1
ty/la   at/rv     #11  $81
prog Mod, 6809 obj, Ew-en, r/o

All it does is calculate numbers and print them to the screen.
