exit code of last failed recipe

Hello,

How can I get the exitcode of last failed recipe?

say I have rc file like this

:0
$DEFAULT

:0 e
{
# If delivery failed to $DEFAULT (say the reason is "can't create 
output" (73)), is it possible to get either "can't create output" or 
"73"? If yes what is the magic string? as $? returns the exit code of 
last executed external program, I can't use it in my case.
}


Thanks in advance
