ABSTRACT
The commands that are introduced and the sections in which they are premiered are as follows:
== (5.1) > (5.1) >= (5.1) | (5.1) < (5.1) <= (5.1) ~= (5.1) Ctrl-] (5.1) Ctrl-(5.1) else (5.1) elseif (5.1) end (5.1) if (5.1) case (5.2) otherwise (5.2) switch (5.2) for (5.3) break (5.4) Ctrl-C (5.4) while (5.4) tic (5.5) toc (5.5) find (5.7)
Computer programs handle contingencies. That is, they allow for different actions depending on different conditions. This single fact about computers could be considered their defining feature. Their great speed, in contrast, could be considered one of their characteristic features. As one author once said, the quality that distinguishes a computer from an adding machine is that the computer can do “ifs.”
