 === sets and ranges ===
-For each of the ranges to check, you give the set-id as a '''WORD''' value (i.e. with a 00 following, e.g. set-id 5 becomes 05 00, or - in case of a callback result - by setting the high bit, e.g. 05 80), followed by the low and high limits of this range. &nbsp;The first range that matches will be used.
+For each of the ranges to check, you give the set-id as a '''WORD''' value:
 The various \b, \w, and \d escape sequences can be useful for <min-range> and <max-range>. See [[GRFActionsDetailed#Byte order|the discussion of escape sequences]] for further information.
