Use SetErrorMode():
Module('WinAPI')
SetErrorMode(UNSIGNED),UNSIGNED,PASCAL
end
Here is a snippet:
If (( DriveType = Drive_Removable) and LOC:NoFloppy )|
or (( DriveType = DRIVE_CDROM ) and LOC:NOCD )
Return
end
DummyLong = SetErrorMode(1) !Get control from Windows
SETPATH( Clip( DQ:Drive ) & ':\')
IF ~ERRORCODE()
Add( DriveQ )
End
DummyLong = SetErrorMode(0) !Give control back to Windows
