asterisk users - Aug 2007 - How to write a function with a return value in Asterisk

Hi,
 
Is it possible to write a function in Asterisk, that returns a value?  Sort
of like any programming language allows?
 
For example, I`d like function ReturnSipReg to return the right
SipRegistration to dial, based on some value so that I could use it in my
dial plan:
 
i.e:
 
exten => 1234,1,Dial(SIP/ReturnSipReg(John)) 
; would dial John's extension, which I don't know at this point to which
Sip
Registration it's associated. ReturnSipReg would find that out for me.
 
 
Unfortunately, doing it in two steps (by setting a variable and using it
after) can't be done, I need it to all be done in the same Asterisk
priority. See my previous email for background ("Buddy watch and the hint
priority - brain teaser").
 
 
Any help is extremely appreciated.
 
Mike

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.
