Change in varnames between 7. and 8.

Maybe I'm wrong.

But it seems that the way a variable is named is different.
Old release: __
New release: //

Is this correct?
What is the impact? Can you modify an old odcl file in the new IDE?

You can modify an old file, you just need to be careful if you mix styles in the same file. In {2} there is a utility for updating older projects.
