Given: global values, idx, nridx
probe begin {
  nridx = 0
  values[idx=1] = 10
  values[idx=2] = 20
  values[nidx=3] = 30
  printf ("optarridx.stp %d %d %d\n", values[1], values[2], nidx)
  exit ()
}

begin /* <- begin */
  # locals
  nidx:long
{
(values[1]) = (10)
(values[2]) = (20)
(values[(nidx) = (3)]) = (30)
printf("optarridx.stp %d %d %d\\n", values[1], values[2], nidx)
exit()
