Description SCL(194) is used to convert the unsigned binary data contained in the source
word S into unsigned BCD data and place the result in the result word R
according to the linear function defined by points (As, Ad) and (Bs, Bd). The
address of the first word containing the coordinates of points (As, Ar) and (Bs,
Br) is specified for the first parameter word P1. These points define by 2 val-
ues (As and Bs) before scaling and 2 values (Ar and Br) after scaling.
The following equations are used for the conversion.
Points A and B can define a line with either a positive or negative slope. Using
a negative slope enables reverse scaling.
The result will be rounded to the nearest integer. If the result is less than
0000, 0000 will be output as the result. If the result is greater than 9999, 9999
will be output.
