You can't, because there is no reason for it. There are only three 
possibilities for applications that don't set a channel variable:

0 : signals normal completion, and the dialplan continues
'0' - '9' or 'A' - 'F' or '#' or '*' : signals normal completion and 
jump to that extension
anything else : signals failure and the call is hung up

Applications generally only return zero or non-zero, so there is no 
reason to be able to retrieve that result, because if it's non-zero the 
call has already moved to the 'h' extension (if it is present). There is 
no lack of documentation here, because application result codes have no 
purpose or value being read or used by code in the dialplan.
