One method is to compile the script into a DLL with MS vc++, then load the DLL through a small ''stub'' program in vuser_init. The DLL must be compiled to use the C calling conventions, not C++, then the functions in the DLL can be called from the LR script. You're not strictly speaking passing an EXE, but the ''heart'' of the script will be compiled to the DLL level.

vuser_init() {

lr_load_dll(''dllfilename'');

my_dll_init_function();

return 0;

}

Action() {

my_dll_action_function();

return 0;

}

vuser_end() {

my_dll_end_function();

return 0;

}

Add the DLL to the list of files to be copied to the LG in the scenario.
