The DoubleSpace Stacker Conversion routine online help contains the
following statement:
You can also convert a Stacker volume file from the MS-DOS prompt
using the dblspace /convstac command. For more information, type
HELP DBLSPACE /CONVSTAC at the command prompt.
This is incorrect; there is no help about DBLSPACE /CONVSTAC in MS-DOS
Help.
NOTE: You cannot use the DBLSPACE /CONVSTAC command until you have
converted your Stacker-compressed drives to DoubleSpace-compressed
drives. You can then use DBLSPACE /CONVSTAC to convert your Stacker
compressed removable media disks to DoubleSpace-compressed removable
media disks.
