I am in the process of archiving power pc instructions that do not
contain null... I have come to the decision that if I could generate a
list of all possible unique 4 char combinations for a given list of
alpha numeric chars then I could quickly sort the rest out in gdb...

My question is does anyone know how to programatically do this? Do i
need to make use of bit shifting or something? I need only a program to
print the list to the screen or something simple. Example output would
be ...

AAAA
BBBBB
....
AAAB
AAAC
...
and so on but ONLY unique posibilities.
