PAD (var, size) or PAD$ (var, size)
Returns a string equal to the input string var (which must be string format) padded with trailing spaces out to the length specified by size. In other words, this is the opposite of STRIP(var). If size is less than the current length of var then it functions just like the LEFT(var, size) function.
