Paul,

I wear my ignorance on my sleeve sometimes...;-)  I had thought the
mainframe was all hardware advances, because it gets about as much exposure
in the press as the iSeries does.  I shoulda known...  Do you if there are
many on iSeries, that also understand the modern mainframe...?  I always
figured they were oil and water.

Thanks for the education...
