The monochrome status and error code display line is complimented with
another field, progress reporting. Progress reporting is a four "nibble"
wide field (just after the error field) that gives an indication of progress of
the test module by increasing its count from zero after the first pass and
during each subsequent pass. The progress count is always initialized at
the beginning of each pass.
