Are there any tools that help convert a program that was written in TV 6.3 to 6.5. If its a large program, it will be a very long task. I use lots of addvertex, addface, etc commands and see its formatted differently with TV 6.5.
No. Use 'Find and Replace' - there is a slew of options on how to match the search pattern and where to search.
If your code is clean and not full of Dim jj ,hh, kk then it shouldn't take long.
You'll still need to fix errors where some functions have changed though.
