Help regrading framework implementation

I want to create a keyword driven framework here in test complete.

I want to have it similar up to some extent(high level design),as we have implemented previously in QTP.



basic functionality i would like to have are as follows

1)Name map would reside in the excel sheet.

2)For each keyword, there would be function/procedures attached with the test.

3)one of the excel range would work as some input parameter for the keyword it is associated with.

I could read the excel through the DDT,but how would i be able to pass the name map and other parameters to the function/procedures(depicted as keyword in excel).?

Also is it possible to add the function unit(function/procedures) at run time through test complete object model.



any help or guidance would be much appreciated.

Thank you
