What PID's/ SID's/FID's are

[Don Bradner]

Ralph, I'm glad you posted your explanation - I'm not surprised that there were
questions.

As a 3-year user of VMSpc, I find the advantages to be several. First, my mind
processes digital data better. I see 65 MPH more readily than I do a needle
pointing at the corresponding spot on the analog gauge.

Second, I get data that is not otherwise available. I really like, for example,
to be able to see the cruise set speed, so I know when I hit resume what it is
going to take me to. Worked better on the last coach where that number was
retained between power-on sessions, but it still is good after spending 30
minutes passing through a town off the cruise.

The remaining thing is the ability to set yellow and red alarms at my own choice
of set points. I'm going to get a red light from coolant temperature well before
I'm in trouble, and I hope the same will be true for coolant level. My copilot
keeps an eye on the laptop, and alerts me the moment any status changes from
green to any other color, without her having to know what numbers are "bad"
ones.
