using PROG_MEM in static struct… howto?

I shall store in flash memory the string which names the relative pin.
And my pointer can stay in the RAM.

I watch some code with lines as:

static const prog_char *label PROGMEM = "my string";

I would initialize my structure writing something like:

  static intfPulse pulses[] = {
    { 13, 0, "LED" }
  }

Do you see what I mean?
