This podcast examines using Arrays in Pascal to store and manipulate lists of values.

Use the case statement to jump to a branch with a matching value, and see a simple use of this in SwinGame.

Repeat code 0 or more times with the While Statement in Pascal, then see how this can be used to schedule sound effects.

See how to branch code with the if statement in Pascal and how this can be used in the game loop to handle user input.

Learn about the use of the compound statement in grouping code within your programs.

Learn how to repeat steps 1 or more times using the Repeat Statement in Pascal, and how this can be used to create a game loop.

A program may consist of many functions and procedures. To help you manage your code, Pascal code can be divided across units. This podcast shows you how to create and use units.

The var modifier in Pascal allows parameters to be passed by reference as in/out parameters. This podcast looks at the use of out parameters to return values from procedures.

Values can be passed to functions and procedures using parameters. This podcast looks at passing parameters by reference using the var modifier to create in/out parameters.

Having created your own procedures, the next step is to create functions. In this podcast you will see how to create and use your own functions.
