Basic Programming Concepts
**************************

   This major node attempts to define some of the basic concepts and
terms that are used throughout the rest of this Info file.  As this
Info file is specifically about `awk', and not about computer
programming in general, the coverage here is by necessity fairly
cursory and simplistic.  (If you need more background, there are many
other introductory texts that you should refer to instead.)
