Once you have set both the connection and system all you need to do is call the appropriate method on the appropriate object. Hence to "Load" a "customer" record we issue the "Load" method on the "oCustomers" object as follows;

loITRDS.OCUSTOMERS.Load("2744262")

Of course again we should check for errors. As this method returns either true or false we can do the following;

If not loITRDS.OCUSTOMERS.Load("2744262")
* Handle error here
Endif
