This looks like a function:

function Find_Other (Source : Whatever; Item : Whatever_Else)
return Thingy;

Where
Whatever      is the type of Source in your code
Whatever_Else is the type of Source.Reference (Pos)
Thingy        is the type of Pos

You would also want a similar function that uses "=" rather than "/=":

function Find_Equal (Source : Whatever; Item : Whatever_Else)
return Thingy;

Then all the cases where you're writing code like your example would be 
replaced by a call to one of these functions.

It's probably more complicated than that.
