PHONEPER version 2.0 : Phone number permutation generator
by Adam Frampton and Evan Johnson
PHONEPER will take a given phone number and make a file (about 20K) of
all possible letter combinations from that phone number. Since the number
1 is not associated with any letters, a "1" is inserted instead of a letter.
C:\> phnper2 6528120
will generate a file called PHONE.PER with all permutations. (Note that
there can be no spaces or dashes in the phone number). (Also note that if
you want to keep this file, you'd better rename it, or it'll be overwritten
next time the program is run).
1.0 : First public release. Written in QuickBasic, this version was slow,
inefficient, and all-around worthy of its parent language.
2.0 : Independently rewritten by Evan Johnson in Turbo C++, this version is
fast, efficient, and all-around worthy of its parent language.
