# provides sets of three highly-acceptable words to work into your
# material. Your audience will never know that the phrases don't
# really mean much of anything because they sound so great! Full
# instructions for running are given in the program.
#
# "This version of Buzzword was written by David Ahl."

#
# Porting Notes
#
# The original program stored all 39 words in one array, then
# built the buzzword phrases by randomly sampling from each of the
# three regions of the array (1-13, 14-26, and 27-39).
#
# Instead, we're storing the words for each section in three
# separate arrays. That makes it easy to loop through the sections
# to stitch the phrase together, and it easily accomodates adding
# (or removing) elements from any section. They don't all need to
# be the same length.
#
# The author of this program (and founder of Creative Computing
# magazine) first started working at DEC--Digital Equipment
# Corporation--as a consultant helping the company market its
# computers as educational products. He later was editor of a DEC
# newsletter named "EDU" that focused on using computers in an
# educational setting. No surprise, then, that the buzzwords in
# this program were targeted towards educators!
#
#
# Ideas for Modifications
#
# Try adding more/different words. Better yet, add a third
# array to the WORDS array to add new sets of words that
# might pertain to different fields. What would business buzzwords
# be? Engineering buzzwords? Art/music buzzwords? Let the user
# choose a field and pick the buzzwords accordingly.
