An example program

xxx Need more intro and description of program

typedef struct {
   char str[100];
} String;

@process server(@share @reply r, @share @bag s)
{
   double f;
   int i;
   String *tmp;
while (1) {
      @resource (r, f) {
         i = (int)(1000.0 * sin(f));
tmp = (String *) malloc(sizeof *tmp);
         sprintf(tmp->str, "Resource got %f, writing %d
n", f, i);
@put!(s, tmp);
} @reply i;
}
}

@process client(int i, @share @reply r, @share s)
{/* @share @bag is equivalent to @share */
   String str;
double v = i / 3.0;
   @call(r, v, i);
sprintf(str.str, "Call sent %f, got %d
n", v, i);
@write(s, str);
}

eMain()
{
@share @reply r;
   @share @bag print;
   @init(r);
   @init(print);

   @subordinate (i @for 3) server(r, print);
   @cooperate (j @for 10) client(j, r, print);
   while (1) {
      String *str;
      /* Remove everything from the print context */
      @select {
         @get!(print, str) {
printf("%s", str->str);
            free(str);
}
         @else {
            /* Only when the context is empty */
            break;
         }
      }
