Loop - quit

The "loop" statement has the form:

        loop STATEMENT

A "loop" command repeatedly executes the following statement or block. A "quit" statement is used to exit from any point (or points) within the loop. Usually a "quit" is used in an "if" statement so that the loop exits under certain conditions. For example:

        loop    begin

                InputGuess;

                if Guess = Number then quit;

                TestGuess

                end
