9.   Procedures Blocks: These blocks let you create reusable sets of instructions.
                     They help you avoid repeating code and keep your app organised.

                     Example:


                                to  procedure2  Collects a sequence of blocks together into a group.
                              result



                                 to  procedure  Same as a procedure do block, but this procedure returns
                              do
                                               a result when called.





                        CREATING AN APP



                 In this activity, you will create an app that shows a multiplication table when a
                 number is entered. The app will display the results of multiplying the number by 1 to 10.

                 To make the Multiplication Table App, follow the given steps:

                 Step    1    Click on the New Project button and name it Multiplication_Table.

                 Step    2    Click on the Screen1 option and set AlignHorizontal to Center: 3 and

                              AlignVertical to Top 1.

                 Step    3    Drag a Label from the Palette to the Viewer, then set its properties: Text
                              to Multiplication Table, FontSize to 30, check FontBold and align it to
                              Center.
