MOPAC Point Charges

I'm getting my feet wet running some QM/MM calculations, and I noticed a difference between how MOPAC and Orca calculations are set up. When I run with Orca, a sizeable point charge file is created and read by the program. However, I can't find point charge information anywhere in the working folder for MOPAC calculations. Is this because MOPAC doesn't have support for point charges? Or is there possibly a keyword that I'm missing in the input?
