Commodore PC 20 - Wildcards; The? Wildcard

Using the? wildcard
Wildcards
If you are using multilevel directories, you will find it easier to
search for files on your disks if you use two special characters,
called
wildcards. The wildcard characters are the asterisk (.) and
the question mark (?). They are useful in MS· DOS command lines
because they give
you flexibility when you are specifying paths
and files.
The ? Wildcard
A question mark (?) in a filename or filename extension means
that any character can occupy that position. The following com-
mand, for example, lists all filenames
on the default drive that
begin
with the characters memo, that have any character in the
next position, that end with the characters aug, and that have an
extension
of. txt:
dir memo?aug.txt
Here are some examples of files that might be listed by the above
command:
MEMo2AUG. TXT
MEMo9AUG.TXT
MEMo8AUG.TXT
The * Wildcard
c'
L,
An asterisk (.) used in a filename or filename extension means C
that any character can occupy that position or any of the remain-
ing positions
in the filename or extension. For example, the fol-
lowing
command lists all the directory entries on the default drive C
with filenames that begin with the characters memo and that have
an extension
of . txt:
dir memo*.txt c==
