Parameter Procedure return value in the parm list

Hi,
 
I'm wondering if there's a way to code a prototyped call and be able to
signify that a parameter will have a value returned to it.
For example...
 
(all code is typed in, not copy/pasted, so columns will be off)
 
D dtrAmount   PR
D   order                 7   0   const
D   amt1                 9P 2
D   amt2                 9P 2
 
If I have the following statement buried in the code, I can write a
comment to say that amt1 and amt2 will have values returned, but I'd
rather have the code itself tell me.
 
dtrAmount( order : amt1 : amt2 )
 
I'm wondering if there's something like the below statement that makes
the parameters that will have values returned to them stand out.
 
dtrAmount( order : &amt1 : &amt2 )
 
 
Thanks,
