=====Array arithmetic=====

//by Richard Russell, March 2014//\\ \\ **LB Booster** supports the ability to perform arithmetic operations on whole arrays, that is the operation is performed individually on every element of the array without you having to code a loop. For example you can add, subtract, multiply or divide arrays as follows:\\ 
<code lb>
      a() = b() + c()
      a() = b() - c()
      a() = b() * c()
      a() = b() / c()
</code>
Note that the arrays must all be the same size. If each array has a maximum index value of 10 (the default) the first of the above examples is equivalent to (but will run much faster than) this code:\\ 
<code lb>
      for i = 0 to 10
        a(i) = b(i) + c(i)
      next i
</code>
You can also add, subtract, multiply or divide each element by a scalar numeric value as follows:\\ 
<code lb>
      a() = b() + n
      a() = b() - n
      a() = b() * n
      a() = b() / n
</code>
The + (concatenation) operator can be used with string arrays:\\ 
<code lb>
      a$() = b$() + c$()
      a$() = b$() + "!"
</code>
Finally, you can assign the same value to every element of an array in one operation:\\ 
<code lb>
      a() = 4 * atn(1)
      a$() = "Hello world!"
