The RunRumbaMacro method is supported only if the Rumba compatibility feature is installed (this feature is installed by default). When the RunRumbaMacro method is called from a VBA macro, the Rumba macro is converted to VBA code and the converted code is placed in the RUMBA_Macro module. The converted code is executed the next time the macro runs. Do not prepopulate the RUMBA_Macro module with Rumba code. This can slow execution and possibly cause other problems.
