This sample demonstrates the use of script with several .rvl.xls workbooks each having few sheets (attached). This is a workaround-type of approach for Rapise 5.1, until the release of Rapise 5.2, since the new version  has "Include", "Scenario" and "Call Scenario" commands in RVL 5.2. This workaround is upgrade safe (it will keep working even in the future when we have 'Include' etc).
This sample also demonstrates passing data between sheets using global variables.  It is possible to make hierarchical scripts with more complex call logic using the same approach.
