If you enter the MATCH command but omit the
text
parameter, the RDFSCAN prompts you
for a match pattern.
To disable pattern matching, merely press the RETURN key at the prompt without entering a
pattern.
When entering a match pattern, you can use asterisks (*) and question marks (?) as wild-card
characters.
When pattern matching is enabled, the DISPLAY function is automatically enabled; when pattern
matching is disabled, the DISPLAY function is automatically disabled.
Table 9-1 shows the symbols RDFSCAN uses in pattern matching.
