hope i did right - 9 pages (4 on both sides) without header and dates
indexing a page with perhaps 80-90 single space names and no header for dates [United States—Enlisted and Officer Muster Rolls and Rosters, 1916–1939 [Part J][M3W3-YM6]]. I re-read all the instructions given and this circumstance was not given. I also looked at plus 4 and minus 4 pages in front and back which were the same type of record (i.e. tantalizing many names on every page BUT no header/dates). The program wouldn't let me go farther than 4 pages either way and gave warning that pages beyond that were "forbidden."
I Read through the names on my page and found a couple where it said they were in the hospital "since X-X- 1919". Not having any other way of resolving this, my best judgement was to assume that all the records were from that year and I extracted all of them using <blank> on the month and day fields but putting "1919" on all of the names.
If someone with more authority than I can go back further than 4 records to find the real date, perhaps they also have the where-with-all to edit what I've done with their updates. (I don't know what the rationale could be to prevent us from looking back or forward more than 4 pages). At least I will have done most of the hard typing.
