6.3.1 Correcting a File After Creation

Bad data values can enter CA MICS files from various sources.
Among the reasons for such problems are modifications made to
CA MICS logic, operating system and measurement device
malfunctions, and misapplied data.

Data integrity problems may be of several types.  Some of the
data values can accurately be reconstructed, but some cannot.
Usually, recovery of maximum and minimum value data elements
and accumulated data elements is very difficult, while
recovery of computed data elements is relatively easy.
