Is there a disk in a: drive?

If you have QB45, try....

DEFINT A-Z
TYPE RegTypeX
AX AS INTEGER
bx AS INTEGER
CX AS INTEGER
dx AS INTEGER
bp AS INTEGER
si AS INTEGER
di AS INTEGER
FLAGS AS INTEGER
DS AS INTEGER
ES AS INTEGER
END TYPE

DECLARE FUNCTION DiskFree& (Drive$)
PRINT "There are"; DiskFree& ("A"); " bytes free on A:"

FUNCTION DiskFree& (Drive$)
DIM InRegs AS RegTypeX, OutRegs AS RegTypeX

InRegs.AX = &H3600
InRegs.dx = ASC(UCASE$(Drive$)) - ASC("A") + 1
CALL interrupt(&H21, InRegs, OutRegs)
IF OutRegs.AX = -1 THEN
PRINT "Invalid drive or disk not in drive."
EXIT FUNCTION

Temp& = OutRegs.AX
temp2& = OutRegs.dx

DiskFree& = OutRegs.AX * OutRegs.bx * OutRegs.CX

END FUNCTION
