(Now with some actual content.) The standard justification for spin loop is
that the area of code in question is executed *very* frequently and is *very*
short. In other words, not worth the overhead of an actual WAIT nor the delay
in having to get redispatched afterwards. Spin loop is not an

The Visara is a CCA-3074. 3074 is FICON point-to-point connected.
Visara terminals are connected by TCPIP through a switch on a
private network, and defined as "hot" consoles. I don't think
the SSL option was used since it is a simple private network.
The HMC 3270 option was attempted and also
Don,
Is your Visara connected via OSA-ICC? Does the console in question receive the
OSA-ICC three line display?
You didn't indicate the reason for running Standalone DFDSS, did you get a new
processor or are you setting up a new DR environment.
The reason I ask these questions is that we just
