[time-nuts] HP 5335A and using the HPIB for control

What??? As a software developer for 30+ years I have a major problem 
with that!!
I have done HPIB programming before, it's not very hard.  What type of 
programming was he talking about?

I'm setting up my own "time lab" right now.  I just got a HP 5370A and a 
HP 5335A.
I already have a 5334A, 5334B and a pair of 5385As, and a NI PCI HPIB 
card that I just put in a Linux box.
I plan on using the card to collect data from the counters. Starting 
with logging measurements.
I don't know if any of my counters support reading while actively 
counting.  (Reading and clearing the counter
while the gate is open and it's actively counting.)

Do other "time-nuts" make use of HPIB?
