Can't say that I understand your problem. Do you mean that gp.Create("MyTemplate.otp") doesn't work? If so, how does it fail?
According to the LabTalk programming guide page.cntrl = 0 or 4. At any rate, how would that property overcome your problem?
...OK, I see now that you got page.cntrl=16 from the section of Help > Origin shown at the URL below. If you are entering the property in the script window you must use page.cntrl=16 rather than LabTalk.page.cntrl=16.
