' This is another simple demo of the PBClone routines. It allows you to
' play a digitized sound file (.VOC format) on a SoundBlaster. The SBSIM
' driver, which is provided with SoundBlaster, is required.
' Syntax:
' PLAYVOC vocname[.VOC]
' The file extension is optional.
' Typically, this would be converted to an .EXE file using these steps:
' BC PLAYVOC/O;
' LINK PLAYVOC/EX,,NUL,PBCLONE;
DECLARE SUB SBGetActive (FM%, DskVoice%, MemVoice%, Auxiliary%, MIDI%)
DECLARE FUNCTION SBInt% ()
DECLARE SUB SBInitSrcFile (BYVAL DriverNr%, FileName$, ErrCode%)

DECLARE SUB SBStop (BYVAL DriverNr%)
