| + | ===== Variable Array Access ===== | ||
| + | |||
| + | If a variable contains a sequence of numbers separated by comma (,) then you can access that variable using array notation (eg `MyVar[5]`). So if variable MyVar has a text value of `10,20,30,40,50,60`, MyVar[5] will return 50. | ||
| + | |||
| + | The index is itself an expression, so it can be arbitrarily complex. | ||
| + | |||
| + | Indices are 1-based, so MyVar[1] is the first element. If the index is 0, the size of the array is returned (so MyVar[0] would be `6`). If the index is less than zero, the array is indexed from the end (so MyVar[-5] would be `20`). | ||
