Calling Btrieve in Non-ANSI Mode

Btrieve does not normally conform to ANSI standards but, by default, the Xfh2btr call conversion module makes the necessary calls to the Btrieve run-time system to force it to emulate ANSI behavior. You can, however, choose to operate in non-ANSI mode by setting the FILETYPE Compiler directive to FILETYPE"6".

In this mode of operation, each Micro Focus File Handler operation is mapped to the nearest Btrieve run-time call and no attempt is made to conform to ANSI standards:

• Any run-time system switches you set in this COBOL system are ignored by the Xfh2btr call conversion module
• The operation proceeds as if you had specified the NODETECTLOCK Compiler directive
• No attempt is made to re-position the current record pointer (CRP) after deleting, re-writing or writing records in the file
• Each COBOL I/O call is mapped to its nearest corresponding Btrieve run-time system call as follows:

  COBOL I/O Call	Btrieve Run-time System Call
  OPEN	Open
  CLOSE	Close
  WRITE	Insert
  READ	Get
  START	Get
  DELETE	Get/Delete
  REWRITE	Get/Delete
  UNLOCK	Unlock
  ROLLBACK	Abort transaction
  COMMIT	End transaction
