///1ASSIGN

  Syntax:

          ASSIGN D:[=[{D:|<device>[<unitnum>]:[<slicenum>]}]][,...]

  Explanation:

       Using the  ASSIGN  command,  on a RomWBW  system  the  drive
       letter assignments can be listed or changed.

       Drive letters can be swapped,  assigned to devices or slices
       or unassigned.

       Multiple (un)assignments can be concatenated using commas.

       A  device or slice  can only be  assigned to  a single drive
       letter.
