>> перевод ODS API mssql2000 на Delphi (написание extended stored procedures)
перевод (как я понял, один из многих) заголовочных файлов
ODS API mssql2000 на object pascal.... для успешной работы необходима opends60.dll...
выполнен с помощью утилиты c2p, её комментарии я оставил...
часть функций, помеченные как устаревшие, не были переведены...
имхо перевод не лишен недостатков, поэтому используйте as is...
добавлю, что у меня всё работает... :)
