Last change on this file since 2884 was 2869, checked in by Takeshi Nakazato, 11 years ago

New Development: No

JIRA Issue: Yes CAS-5841

Ready for Test: Yes

Interface Changes: No

What Interface Changed: Please list interface changes

Test Programs: test_sdsave, test_importasdm_sd, all sd regressions

Put in Release Notes: Yes

Module(s): sd

Description: Describe your changes here...

Filler/writer are changed so that SCANNO is consistent with
SCAN_NUMBER in MS and scanNumber in ASDM.

It affects several regressions and unit tests so that tests
are necessary to be updated. This change should be verified
by the updated unit tests/regression tests.
