Array functions

TEL grammar includes a number of array functions that you can use to examine and modify arrays:

•	.size() – returns the number of elements in an array.

•	.isEmpty() – checks whether an array is empty.

•	.clear() – clears all elements in an array.

•	.add() – adds an element to an array.

•	.remove() – removes an element from an array.

You can also use the general functions type(), toInt(), toDouble() and toString() to examine and modify arrays (see General functions).
