Dealing with the NaN's in the history system in the past week, a question came

I preliminary implemented NaNs into the history system. It works such that if a
device driver returns a read error status, the class driver writes a NaN
(Not-a-Number) into the corresponding variable via the new function ss_nan(). The

Good that you brought up the MIDAS VME API again, since this is still not complete, but
has to be completed soon.
