for lathe a MPL should be the prefix == Mcam Post Lathe
this is a naming format for Mcam before X
The header info should tell you the post capabilities
A mill/turn can be a custom special ( mill/turn is a confusing term )
now a lathe with the milling function look for a lathe with 4 axis or C-axis
ie GENERIC FANUC 4X MT_LATHE.PST
Read the headers in the actual .PST file
