D. Basic Programming Concepts

This appendix attempts to define some of the basic concepts and terms that are used throughout the rest of this Web page. As this Web page 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.)

D.1 What a Program Does  The high level view.
D.2 Data Values in a Computer  A very quick intro to data types.
D.3 Floating-Point Number Caveats  Stuff to know about floating-point numbers.
