Hour of Code: Code with Mary

An output statement will print text on the screen.

A say statements will instruct the computer to speak the expression aloud.

Note that some browsers do not support the say feature in Quorum's online mode.

Use an if statement to have the computer decide whether or not to run certain code.

An if statement requires a condition to be evaluated (variable > 5, variable = 5, etc.) and an end statement to mark the end of the code block.

An if statement can optionally contain an elseif statement to test another condition or a default else statement (or both) to handle any other possibility not listed.

More information on if statements can be found here.

When we want to run a section of code repeatedly, we use a repeat statement to create a loop.

Like an if statement, a repeat statement requires a condition for stopping and an end statement.

We specify the condition for stopping the loop by using one of these formats:

repeat {number} times,

repeat while {condition} or

repeat until {condition}.

More information on repeat loops can be found here.

Actions are used to reduce the amount of duplicate code in a program and to make it easier to read.

To create an action, use the keyword action followed by the action's name, which usually starts with a capital letter.

The computer always starts executing a program at the Main action, but if the program has only one action, Quorum will automatically insert the program code into a Main action.

If a program has actions besides Main, the action Main must be defined somewhere in the program.

To execute an action at a particular point in the program, type the name of the action followed by parentheses.
