It sounds as if you might be interested in "Formal Parameter Modes", defined in 
ARM 6.2:

http://www.ada-auth.org/standards/rm12_w_tc1/html/RM-6-2.html

The mode defines the direction of data flow between the subprogram and the 
caller: "in" means data flows from the caller into the subprogram; "out" means 
data flows from the subprogram back to the caller; what "in out" means is left 
as an exercise for the reader.
