Hi
Accoridng my knowledge  keyword driven frame work nothing 
but the functions called based on keywords
inthis frame work first of all we have to create 7 folder
like this 
lib,ropsiterey,rocovery,testdata ,testscript,log,env create 
the tests save in vbs over the file creation we have to go 
to new qtp programe  call functions 
example yahoo!()
gmail()
go to test and mention the test paths in library files 
here vb script save in vbs 
recovery tests in .qrs
repository tests in .tsr
add these three files 
and run the frograme
