To be picky, PCML doesn't make the call n-tier. The toolbox does that (more specifically the ProgramCall class which acts as a wrapper over the OS/400 host server). PCML is simply a shorthand way of invoking the toolbox classes. It externalizes the program information in an XML file and makes processing a call a little easier for the programmer (especially as far as data conversion). There is actually a second generation of this technique called XPCML which uses a well-formed XML document.
True ... I was making a comparison between NMI / SQL method and the ProgramCall functionality. david
