1.1       root        1: #print
                      2: Sometimes ? is too flexible, and you
                      3: only want to allow a few characters.  For example,
                      4: you might want to abbreviate
                      5:   ls memo.ab memo.ac
                      6: without picking up "memo.ad", memo.ae", etc.
                      7: You can match one of a set of particular characters by 
                      8: putting them in brackets "[]" in the list you use with "ls".
                      9: For example,
                     10:   [bc]
                     11: matches either b or c but no other letters,
                     12: so "ls memo.a[bc]" is the abbreviation for
                     13: "ls memo.ab memo.ac".
                     14: You can have as many characters as needed between [ and ].
                     15: 
                     16: Type the "ls" command that recognizes
                     17:   a1cat
                     18:   a2cat
                     19:   a3cat
                     20: and no other files.  Then type "ready".
                     21: #create a1bat
                     22: #create a1cat
                     23: #create a2cat
                     24: #create a3cat
                     25: #create a4cat
                     26: #create acat
                     27: #copyin
                     28: #user
                     29: #uncopyin
                     30: #match ls a[123]cat
                     31: #match ls a[1-3]cat
                     32: #match ls a1cat a2cat a3cat
                     33: You were supposed to use a[123]cat.
                     34: Imagine doing it your way with 10 files.
                     35: #log
                     36: #next
                     37: 8.1a 10
                     38: 8.2a 5
