Hi Matt, Try this
DEFINT A-Z
FUNCTION GetCurrentDirectory$ (Drive$)
'Drive$ = "c"
'*need to check if there is a disk in the drive before calling
'function on a floppy
Drive$ = UCASE$(LEFT$(Drive$, 1))
Drive% = ASC(Drive$) - 64
DIM directoryString AS STRING * 64
directoryString = directoryString + CHR$(0)
inreg.ax = &H4700
inreg.dx = Drive%
inreg.ds = VARSEG(directoryString)
inreg.si = VARPTR(directoryString)
INTERRUPTX &H21, inreg, outreg
IF (outreg.flags AND &H1) = 0 THEN  
 GetCurrentDirectory$ = Drive$ + ":\" + directoryString
 ELSE
 BEEP: GetCurrentDirectory$ = "Error"
 END IF
END FUNCTION
