Array+arithmetic

//by Richard Russell, March 2014//

code format="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 format="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 format="lb" a = b + n   a = b - n    a = b * n    a = b / n code The + (concatenation) operator can be used with string arrays: code format="lb" a$ = b$ + c$ a$ = b$ + "!" code Finally, you can assign the same value to every element of an array in one operation: code format="lb" a = 4 * atn(1) a$ = "Hello world!" code
 * 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:
