- 21CastingConverts data types e.g str()
- 22ConcatenationJoining of multiple strings together
- 23ProcedureIt can be called from the main program or from another procedure
- 24Case statementsUses a variable instead of a condition to determine which instructions should be executed. An alternative to if statements.
- 25ArraySeveral items of data all of the same type stored under one identifier
- 26specified parts of an array1)Identifier
2)it's dimension
3)it's data type
4)the maximum and minimum index values - 27While loopsa loop in which the condition is tested first, every time the condition is true the instructions is executed
- 28Repeat Until loopsThe instructions are executed, after all the instructions are executed the condition is tested. The loop ends when the condition is true.
