Thanks for the suggestion.
I'm upgrading my POV-STL-CAD translator from 32 to 64 bit, and I realized that
before translating the pov files I need to normalize all the various syntax

If I don't standardize the syntax, compiling the database for exports the
entities will become a very complicated mess.
I'll try what you suggest...
