                  Logical Operators

                  Using logical operators,  you can combine two or more relational operators  to
                  produce a single true/false result. These blocks allow you to further refine your

                  comparison of values.

                                                 The result is true only if the two expressions are true.
                   1.  AND


                                                 The result is true only if either of the expressions is true.
                   2.  OR


                                                 The result is true only if the expressions is false.

                      VARIABLES

                  Variables are used to hold values. These are the data

                  values for which the value can be changed when the
                  code is being processed. There are two ways in which
                  the  values can  be  assigned to  the  variables—by the
                  programmer and by the user.

                  Each programming language has a method or syntax
                  for defining variables. In Scratch, the variables can be

                  created using Variables blocks.
                  To create a variable, follow these steps:

                  Step 1  Click on Variables category of blocks.
                  Step 2  Click on Make a Variable button to open the

                            New Variable dialog box.
                  Step 3  Type a suitable name, for example N1 for the
                            variable in the New variable name text box.                          Variables block
