Enter the coordinates of the m+1 end-points, which define the m line segments,
as shown in the following table. Enter all coordinates in BIN form. Always enter
the coordinates from the lowest X value (X

The following example demonstrates the construction of a linear approximation
with 12 line segments. The block of data is continuous, as it must be, from DM
0000 to DM 0026 (C to C + (2 × 12 + 2)). The input data is taken from IR 010, and
the result is output to IR 011.
