What do you mean, "call"? If you mean, open the particular Excel file as if it is open from windows explorer, then you may use something like this:

	DECLARE INTEGER ShellExecute ;
			    IN SHELL32.DLL ;
			    INTEGER nWinHandle,;
			    STRING cOperation,;   
			    STRING cFileName,;
			    STRING cParameters,;
			    STRING cDirectory,;
			    INTEGER nShowWindow
? ShellExecute(0,"open",fullpath(filename),"","",1)
