Change History (most recent first):
|
|
|
|
<6> 7/30/91 JL Updated Copyright. Change #defines to enums. Reformatted structs
|
|
to match database.
|
|
<5> 1/27/91 LN Checked in Database generate file from DSG.
|
|
<4> 03/07/90 JAL Changed records for C Plus Plus support.
|
|
1.0 CVC 11/02/1989 First time add the file to CInclude
|
|
|
