Re: Erratic TInterpreter::GetInterfaceMethod behaviour?

Hi,

I understand the problem now, but it seems strange that the LoadMacro reported success when it clearly didn't work. I have now added TApplication, and it is fine.

Is there documentation somewhere for this behaviour? The only references to TRInt/TApplication that I can find in the users guide are in relation to running GUI applications.

Thanks,

Nick
