24? What's 24? There are _26_ letters in the alphabet! Or
was "24" a base _11_ number? And if so, what extra digit
were you using other than your fingers? :-)

For the sake of theoretical responses, here's the
"Programming Perl" explanation:
=> The autoincrement operator has a little extra built-in magic
=> to it. If you increment a variable that is numeric, or that
=> has ever been used in a numeric context, you get a normal
=> increment. If, however, the variable has only been used in
=> string contexts since it was set, and has a value that is
=> not null and matches the pattern /^[a-zA-Z]*[0-9]*$/, the
=> increment is done as a string, preserving each character
=> within its range, with carry:
=>
=> print ++($foo = '99'); # prints '100'
=> print ++($foo = 'a0'); # prints 'a1'
=> print ++($foo = 'Az'); # prints 'Ba'
=> print ++($foo = 'zz'); # prints 'aaa'
=>
=> The autodecrement operator, however, is not magical.
I guess by "within its range" implies 3 (not 2) ranges:
[a-z]
[A-Z]
[0-9]
