Operands The contents of the four words starting with the first parameter word (P1) are
shown in the following diagram.
Operand Specifications
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.
