Chapter 7: Programming

Equalities and inequalities

These expressions are used to form the conditional statement in the If clause. They are the basis for looping and other flow control operation in programs.

The ‘=’ (equals) sign is also used as a function to form a substitution command for variables.

You can also enter ‘=’ by simply pressing ;=.
