Btrieve

Btrieve is a transactional database software product based on Indexed Sequential Access Method (ISAM).

isCOBOL is able to interface Btrieve on Windows.

In order to associate the Btrieve file handler to your indexed files, the following setting must appear in the configuration:

iscobol.file.index=btrieve

It’s possible to associate only specific files to Btrieve. For example, the following configuration uses JIsam for all indexed files, except for "file1" that is associated to Btrieve:

iscobol.file.index=jisam iscobol.file.index.file1=btrieve

Indexed files can be associated to Btrieve also through the CLASS clause in the SELECT statement. E.g.

SELECT BTR1 ASSIGN TO BTR1-PATH               ORGANIZATION INDEXED               CLASS "com.iscobol.io.DynamicBtrieve"               ACCESS MODE DYNAMIC               RECORD KEY BTR1-KEY               STATUS BTR1-STATUS.

The wbtrv32 library (wbtrv32.dll) is required in the PATH.

The following features are not supported:

•	Alternate collating sequence

•	START WITH SIZE

•	Transactions
