RE: ProgramCall and ProgramParameter classes

["Joe Pluta " <joepluta@xxxxxxxxxxxxxxxxx>]

This is excellent.  When I get back from my honeymoon, I plan on doing some 
performance tests to compare the various methods of getting data from the 
AS/400 in Java.  Here are some of the methods I see:

1. Calling a program via ProgramCall
2. Calling a program via PCML (though I don't use this much)
3. Calling a program through a JDBC CallableStatement
4. Direct data queue access
5. Direct file access via JDBC, native and non-native
   (what's a better term for "non-native", folks?)
6. Direct file access via toolbox drivers

Can anybody think of others?  Should I include JINI on the list?

I'm not quite sure I understand this, David.  What's a "varbinary", and what 
are its advantages/disadvantages as opposed to a character parameter?
