I'm not aware of anyone developing a compiler mode for HP VMS Pascal (or 
Compaq Pascal as it seems to be called). So feel free to implement it 
yourself (you could start small by only adding the new mode first and 
maybe a compatibility unit for special type declarations that will be 
automatically loaded like the ObjPas unit for modes Delphi and ObjFPC or 
the MacPas unit for the Mac Pascal mode).
