Hi friends,
does writing a code to invoke two separate existing services in a sequence
means web service composition? how is it different?
what is the role of Business process execution Language BPEL in web service
composition?

I would assume that Web Service composition in the context of BPEL/SOA would use a higher level coordination protocol like WS-Coordination (Web Service Transactions specifications). Programmatic composition would be too "static".
