Digium has taken the stance that it's better to set arbitrary variable names 
to arbitrary values rather than allow what many would consider the perfectly 
accepted method of using a $? type of return code in addition to any 
application-specific variables.

It's been a long-standing sore point with me for sure, since there is no 
standard way to see if an application returned successfully or not; you have 
to consult the individual application to see what it sets.
