Creating a Scalar

   

#The syntax for creating a scalar is: $variableName = <value> 
#    in which value may be numeric (integer or float),   
#    string  
#    reference (scalar, array, hash, code, or package)   
#    or boolean (True or False)  

    
    $scalar1 = 'this is a scalar';    # simple scalar assigned 'this is string' 
    $print = 10.0;                    # simple scalar assigned 10 (rounding is done)    
    $print = '10.0';                  # number that is also a string, assigned 10.0.    
    $scalar2 = "this is $print";      # interpolation, assigned 'this is 10.0'  
    $scalar3 = 'this is $print';      # non-interpolation, assigned 'this is $print'    
    $emptyString  = '';               # empty string.
