INT 2fH 4a11H BX=0002H: Dblspace Swap Drive
Expects: AX 4a11H (mux number)
BX 0002H (DoubleSpace fn code)
DL compressed drive number to swap with its host
Returns: AX DoubleSpace API Error Code (0000H=success)
Info: This swaps a DoubleSpace compressed drive's ID with the ID of its
For instance, if drive C contains a CVF▲ named DBLSPACE.000, then
when DoubleSpace starts up, it will mount that CVF as drive J
To set up so the compressed volume is drive C (and set the host
as drive J), you would set DL to 9 (0=A, 1=B,...9=J)
Notes: ■ There is no "unswap" variation of this fn; if you attempt to
swap a previously-swapped drive, this fn returns an error.
■ DBLSPACE.BIN performs disk swapping automatically, based on
settings in DBLSPACE.INI. I recommend against using this fn.
