Hi folks,
I try to compute the ackermann number, but unfortunately my code is
omehow erroneous. Additonally, I need it in hexadecimal form in a text
file. Some ideas how to solve this problem?

Thanks and best regards

CR

function ack,m,n

while (1) do begin
switch m of
0 : return, n+1u
1 : return, n+2u
2 : return, ishft(n,1u)+3u
3 : return, ishft(1u,n+3)-3u
else: begin
if n eq 0 then begin
n = 0u
endif else begin
n = ack4(m,n-1u)
endelse
m--
break
end
endswitch
endwhile
end
