File statistics provide information about each file currently open in the Online system. The value of each file statistic is determined by the activity against that file within the Online.

ASIZE Size of table A in number of pages.
ASTRPPG Table A strings per page.
ATRPG Number of attribute pages in Table A.
BACKOUTS Number of backed out update units since the file was opened. The stat begins incrementing when the file is first opened, and is reset to 0 when the last user closes it. If the file is reopened the incrementing begins again from 0 (rate or total).
BADD Fields added to Table B (rate or total).
BCHG Fields changed in place in Table B (rate or total).
BDEL Fields deleted from table B (rate or total).
BFULLP Estimate of the percentage of table B that is full. This statistic is equal to the table B highest active page (BHIGHPG) divided by the total number of table B pages (BSIZE).
BHIGHPG The current table B high water mark. Same as the Model 204 BHIGHPG parameter.
BLOWPG The lowest active table B page. Same as the Model 204 BLOWPG parameter.
BQLEN The number of pages in the table B reuse queue. Same as the Model 204 BQLEN parameter.
BRECPPG Maximum number of records per Table B page.
BRESERVE The amount of space in bytes on a Table B page on which new records cannot be started. The space is reserved for the expansion of existing records on the Table B page.
