In models

In order to maintain the same behaviour with Mosel 5 as with Mosel 4, employ imports in place of uses for all packages that are not part of the Xpress distribution

• Make sure to always start with the imports statements, and then the uses statements (this is important if the same package is loaded several times, e.g. directly via a uses and indirectly through a dependency via imports).
• If you do decide to work with dynamic packages these must be made available at run time (in particular, this also concerns the BIM files in Insight apps).
