shellexec(excelfilename)

FUNCTION SHELLEXEC
LPARAMETER lcLink, lcAction, lcParms, nWin

lcAction = IIF(EMPTY(lcAction),"Open",lcAction)
lcParms = IIF(EMPTY(lcParms),"",lcParms)
nShowWin = IIF(EMPTY(nWin),3,nWin)

DECLARE INTEGER ShellExecute IN SHELL32.DLL ;
INTEGER nWinHandle, STRING cOperation, STRING cFilename, ;
STRING cParameters, STRING cDirectory, INTEGER nShowWindow

RETURN Shellexecute(vfp_handle,lcAction, lcLink, lcParms, SYS(2023),nShowWin)


** vfp_handle should be 0 **
