Prerequisites
The target logical disk drive and directory must be accessible.
Procedure
1
Set the Operation Code to 17.
2
Store the logical disk drive and directory path, terminated by a binary 0, in the Key Buffer. If you omit the drive name, the transactional interface uses the default drive. If you do not specify the complete path for the directory, the transactional interface appends the directory path specified in the Key Buffer to the current directory.

Result
If the Set Directory operation is successful, the transactional interface makes the directory specified in the Key Buffer the current directory.
If the Set Directory operation is unsuccessful, the transactional interface leaves the current directory unchanged and returns a nonzero status code.
Positioning
The Set Directory operation has no effect on positioning.
