`GET POINT: x, y`

assigns the coordinates of the point indicated by the mouse click to numeric variables x and y.

Progression of the program is to be suspended until a mouse click.

The beam is to be off.

Refer to PLOT LINES

Let A,B be 1-dimensional arrays, M be a 2-dimensional array.

```
MAT GET POINT A,B
```

obtains the coordinates of the points of number of the size of the array.

MAT GET POINT M

Let n be a numeric expression.

```
MAT GET POINT A(n),B(n)
```

Before execution, arrays are re-sized.

MAT GET POINT M(n,2)

```
MAT GET POINT: A(?),B(?)
```

While the left button of the mouse is pressed, the obtained coordinates are substituted for the arrays.

MAT GET POINT: M(?,)

The size of the arrays are adjusted by the number of the points obtained.

If the amount of the arrays has reached the upper bound, the execution ends.
