8.2.6 About Drives
The BHT-100 has logical drives.
Drive B is provided for ensuring compatibility with other BHT series.
If you specify drive name "B:" preceding a filename.extension and open an existing file, then
the BHT will open the file as a read-only file. Executing the
PUT statement to the read-only file
will result in a run-time error (43h).
If you specify drive name "A:" or omit a drive name, the BHT will open the file as a read/write
file.
The
XFILE and KILL statements will ignore drive names "A:" and "B:."
The table below lists the file access details relating to drives.
