Always investigate tests in the order presented in the table below when inspecting

Test, for example, you may also clear errors generated from other tests in the
testing sequence.

b. This test does not run in release G3iV1 EDI 7.0 or later.
c. The Tape Consistency Test does not run in a Standard system.
Tape Data Consistency Check Test (#421)
The software vintage number, translation time stamps, announcement time
stamps, and update file time stamps and identifiers are read off both tapes and
compared. If the comparison shows any discrepancy, TAPE-DAT is alarmed. This
test is run in a High or Critical Reliability Option system. The test is run as part of
the test tape long and as part of weekly TAPE maintenance.
