table, array,defStruct...?

Hello all.

I am writing a small routine that extract some refdes and logical_path/p_Path properties from Allegro to generate a backannotation file for Concept.
Actually, my back annotation file opens the refdes's drawing, edits the refdes's body and write the schematic.
I want to improve it by grouping all refdes for a same sch page.

My main problem is how to proceed: I am looking for the way to store P_PATH (the property in Allegro that shows the schematic location) with all refdes.

So what should I use and how? an array, a table, a defStruct? something like list(sch1 list(C26 C27) sch2 list(IC10 IC22) ...) Thanks in advance for any tips and tricks!
