Comparisons

Abstract

A computer, unlike a calculator, can compare two pieces of information. It can decide whether a statement is true or false and then act accordingly. In order to do this the computer uses the command or keyword IF, found on key U, followed by the word THEN, on shifted key G. IF, like other commands, can be used only when the computer is in keyword mode; the cursor is a K. The command is simply saying that IF a certain statement is true THEN perform the next instruction in that line. See the example below which compares information by using the sign for equals (=) and the sign for not equals (<>).
