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.
