EXPORT command inconsistancies?

[retoa]

Can you explain better what you mean?

I tried to remove the EXPORT command I have in a solve application with custom variable names but it gives a syntax error.
I also tried to change it to LOCAL, it does not give error during check but gives syntax errors in the symbolic view.

Both errors are right, the Prime behaves correctly in this case.

Can you post an example where it behaves different?
