Field identified: data block count

[jasonhanley]

In the Row Size Subheader, I believe 292|568 is data block count := BC (at least in files with only one page).

I discovered this trying to write an sas7bdat file. Both fields must be set for all versions of SAS to read the file.

Dear Jason,

In the Row Size Subheader, I believe 292|568 is data block count := BC (at
least in files with only one page).

I discovered this trying to write an sas7bdat file. Both fields must be set
for all versions of SAS to read the file.

Yes, I agree. I have been able to write .sas7bdat files also.
Here is what I found about those particular fields in the Row Size
Subheader:

280 / 544 4 / 8 medium int, Page for first data row := PD1
284 / 552 2 medium int, Position for first data row
286 / 554 2 / 6 low zeroes
288 / 560 4 / 8 medium int, Page for last data row
292 / 568 2 medium int, Position for last data row

Sincerely,

Clint
