    CONTROL BLOCK

                      Control blocks have looping blocks which are used when the same blocks have to be
                      repeated a number of times. They are colour-coded amber.

                                    Blocks                                        Functions

                                                           This block  pauses  the  running of the  script  for the
                                wait  1 seconds
                                                           number of seconds.

                                If         then            This block executes a set of actions only if a specific
                                                           condition is true. It checks the condition and runs the
                                                           included blocks when the condition holds.

                                If         then            This block allows the program to perform one action
                                                           if a condition is true and another action if it is false. It
                                else                       checks the condition, executing the first set of blocks if

                                                           true and a different set if false, providing a clear choice
                                                           between two paths.

                                repeat   10
                                                           This block repeats a set of blocks for a given number of
                                                           times.

                                                           This block  keeps  on repeating  a set  of blocks till  the
                                forever
                                                           stop button is clicked. It is similar to repeat block and
                                                           expands  automatically  to  accommodate  the  blocks
                                                           you snap inside it.

                              uiz   Bee        b.  Which block category displays text within pop-up bubbles?
