Hi,

I am not sure about your requirement but

Function modules are Global repository Programs, where as Subroutines are Part of Global repository programs.

Function modules can have OPTIONAL paramters, Where as Subrotuines cannot.

Function modules can raise EXCEPTIONS where as Subroutines cannot.

Funtion modules can be called with out giving the TYPE specification, rouine paramters have to be typed.
