It is quite possible to construct programs which run in both an SR9.7 and an
SR10.1 environment using the optimal calls (_cc for SR9.7 and _lc for SR10.1)
for each environment by building an OBJ rather than COFF object and having the
program determine at run time which environment it is running in.
Domain/CommonLISP uses precisely this technique so that the same program can
run in either environment.  Here is an example:

		if DomainSR10 then
		    Name_$Get_Path_LC('/',1,sizeof(RootName),
				      RootName,RootNameLength,Status)
		else Name_$Get_Path_CC('/',1,RootName,RootNameLength,Status);

As long as the string arguments are declared with UNIV, passing in a variable
of type Name_$Long_Pname_T to Name_$Get_Path_CC will work fine.
