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.
