The VBA script wrote in version 9 cannot work in version 10 and greator versions, how can I deal with that?

To make the VBA functionality more multi-functional, stable, and reliable, it is restructured since version 10.0. The name of some interfaces, the calling functions in version 10.0 are changed a lot. Assuming that all the interfaces supported in version 9 are kept in version 10, due to the “restructure” change, the VBA script written in version 9 should be re-written according to the updated VBA API reference document to make it work and align with version 10 or greater version
