SUMMARY
ASSIGN does not check the current name for the disk drive; instead, it retains the &quot;true&quot;, original name of the disk drive for reassignment.

If floppy disk Drive A contains a single file named A.TXT and floppy disk Drive B contains a single file named B.TXT, the following commands cause the file B.TXT to be displayed in the directory:   C> ASSIGN A=B C> DIR A: The syntax documentation for the ASSIGN command can be checked to verify that this is what should happen. The first drive specified is the drive that MS-DOS normally reads and writes to. The second is the drive that you want MS-DOS to read and write to when the first drive is referenced.

It is not quite so intuitive how to restore A to A and B to B. The following example demonstrates how to ASSIGN the drive back to itself:   C> ASSIGN A=A After this command is issued, a DIRectory of Drive A displays the file A.TXT.
