Linear Extrapolation (C: Word Address)
Using 16-bit Unsigned BCD or Binary Data
APR(069) processes the input data specified in S based on the control data in
C and the line-segment data specified in the table beginning at C+1. The
result is output to D.
• Y

= f(X
n
), Y

= f(X
0
)
• Be sure that X
n–1
< X
n
in all cases.
• Input all values of (X
n
, Y
n
) as binary data.
This example shows how to construct a linear extrapolation with 12 coordi-
nates. The block of data is continuous, as it must be, from D00000 to D00026
(C to C + (2
×
12 + 2)). The input data is taken from CIO 0010, and the result
is output to CIO 0011.
In this case, the source word, CIO 0010, contains 0014, and f(0014) = 0726 is
output to R, CIO 0011.
