Invoking C++ program from mvs assembler code

Does anyone have an example of invoking a z/OS C++ program
(XPLINK-compiled) from MVS assembler?

My c++ program contains a standard main routine "int main(int argc,
char* argv[]);", and a few sub-routines.

Do I need to initialize the LE environment before loading the c++ load
module and calling it?  It seems from the 'LE Writing ILC Applications'
IBM doc that a non-LE-conforming assembler program can invoke a c++
main routine.  When I LOAD the c++ load module and BASR, I get a S0C4
(rsn=10) in CEEPLPKA.  From this, I think that the environment must not
be setup correctly.

If anyone can share experience, tips, or an example, it would be much
appreciated.

Thanks,
Ben

You probably have to set up an O/S plist.

LA    R1,OSPLIST

OSPLIST   DC    A(HWZERO+X'80000000')
HWZERO    DC    H'0'

Should you use the mailblocks package and expect a response from me,
you should preauthorize the dissensoftware.com domain.

I very rarely bother responding to challenge/response systems,
especially those from irresponsible companies.

Thanks for your help!  I had not setup my plist correctly.  With your
help, the call to my c++ program works correctly.  Thanks again!
