APPENDIX D.0 DATABASE

The database contains six datapoint types. Each datapoint type represents a specific data format:
whole integers, alphanumeric text strings, etc. The datapoint types are defined in Table D-1; the
paste-up configuration tables are repeated in abbreviated form (no definitions) in Tables D-2
through D-13; and the database is listed in alphanumeric order in Tables D-14 through D-19.

Middle gray tone shading in any cell means it is not applicable.

Light gray tone shading in the default cell of a datapoint description indicates the
datapoint contents are left unchanged after default.

Black shading in the default cell of a datapoint description indicates the field con-
tents are unpredictable after default.

F database is actually embedded within the A

database, as an

A datapoint type equals two F

datapoint types.
