NBS_GET_UPDATED

Determine whether a primitive item or the noticeboard has been updated since the noticeboard was found or this routine was last called

Description:

Check that the ID is not NIL.
If the item is structured get the noticeboard modified count.
If the item is primitive get the item’s modified count.
Return TRUE (1) if the modified count is greater than the count the last time that this routine was called.
Return FALSE (0) otherwise.
Remember the modified count for next time.

For structured items, always use the same ID, since the remembered count is associated with the ID and not with the noticeboard.
