Recursive programs in XCAS.

Fibonnaci example

Code:


fibon(n):=
begin
  if (n == 1) then return(1); end;
  if (n == 2) then return(1); end;
  if (n > 2) then
    return( fibon(n-1) + fibon(n-2) );  
  end;
end;

In general, any CAS code on the HP Prime should port as easily as copy/paste -- WITH EXCEPTIONS FOR A FEW COMMANDS (e.g. idenmat() on xcas is identity() )

Yes, the example of fibon() you provided works on my iPhone 6+ so, recursive programs are possible in PocketCAS. I must be making some mistake(s) in porting the program.
Thank you very much.
