TEXT:00,If match() cannot find what it is looking for in the searched sequence,

TEXT:32,The previous library routines we introduced in this chapter used an
TEXT:16,actual value to match one or a specific group of elements in a sequence.
TEXT:16,The next library routine uses "wildcards" to search for elements in
TEXT:16,sequences. Before we introduce this library routine, we need to discuss
TEXT:16,what wildcards are.
TEXT:32,Wildcards are single substitution characters used in conjunction with
TEXT:16,other characters to make a generic search string. You may have seen
TEXT:16,wildcards at work when you use the DIR command in DOS as follows:
COLOUR:POINTS
