     The following program can be used by LDOS 5.1.x users to transfer files from NEWDOS80 or DBLDOS double density media. In the case of NEWDOS80, source diskettes cannot have extended directories. The program acts as a filter on a designated disk drive. Once the program is invoked, the referenced drive can only be used to read files from the "alien" diskettes. The command procedure to invoke the drive filter is:

>LM=18
CONVDOS :D ({NEWDOS},{DBLDOS},{REMOVE})
>LM=10

Specify "NEWDOS" or "N" if you are going to transfer files from NEWDOS80 double density data diskettes (when track zero is double density). Specify "DBLDOS" or "D" if you are going to transfer files from Percom's DBLDOS, or NEWDOS80 Model I system disks (when track zero is single density). Specify "REMOVE" or "R" when you are finished transferring files and wish to eliminate the filter. A warning... DBLDOS data diskettes do not store the directory track number in byte 2 (relative from 0) of the BOOT sector. Therefore, problems can develop when transferring files from DBLDOS data diskettes.
