#include <freem.h>

int main(int argc, char **argv, char **envp)
{
    freem_ref_t ref;

    /* we're setting a global */
    ref.reftype = MREF_RT_GLOBAL;

    /* access global "car" */
    strcpy(ref.name, "car");

    /* set up the subscripts */
    ref.subscript_count = 1;
    strcpy(ref.subscripts[0], "color");
 

    /* use the USER namespace */
    freem_init("USER");

    /* write the data out */
    freem_set(&ref);
    
}
