PATTERN MATCHING
Pattern matching of file names is available on all Commodore floppys. Pattern
matching uses the question mark (?) and the asterisk (*) to perform operations
on several files with similar names.
The asterisk is used at the end of a string of characters to indicate that the rest
of the name is insignificant. For example:
could refer to files named
or
or
or
FIL*
FIL
FILE1
FILEDATA
FILLER
or any other file name starting with the letters FIL.
The question mark may be used anywhere within the string of characters to in
dicate that the character in that particular position should be disregarded. For
example:
