This example shows how to construct a linear extrapolation with 12 coordinates. The block of data is
continuous, as it must be, from D0 to D26 (C to C + (2 × 12 + 2)). The input data is taken from CIO 10,
and the result is output to CIO 11.

In this case, the source word, CIO 0010, contains 0014, and f(0014) = 0726 is output to R, CIO 0011.
The linear-extrapolation calculation is shown below.
