I strongly disagree on the desirability of suppressing VSAM statistics
in these cases. It would be much better to display them while
indicating that they are incomplete.
The delta in the LISTCAT VSAM statistics correctly reflects the activity
to the VSAM data set between two points in time, as long as you compare
between two points where the VSAM file is closed and also know there
are no intervening OPENs without a valid CLOSE. This is extremely
useful as an activity measurement tool, even if the absolute values are
missing counts from earlier accesses.
I would hate to see one program ABEND make it impossible to get any
statistics from all VSAM datasets used by the program until those
datasets have been reorganized by unload/reload, as in some cases it may
not be practical to reorganize the files for weeks or months.
This also suggests that calling the statistics "INVALID" may be too
strong a pejorative, as all the counts reflect actual activity to the
file - it's just that they do not represent ALL the activity to the file.

This time. however, I am in MarkThomen's corner. Meaningless or invalid
statistics should be marked as such or, better, suppressed.
Moreover, I don't like the caption of this thread.
The word 'bogus' is not a general-purpose pejorative. It means
counterfeited or faked. We are not dealing with anything of that sort
here, and the use of this word here is thus wholly inappropriate, even
perhaps slanderous.
