Example When CIO 000000 is ON in the following example, SIGN(600) converts the
16-bit signed binary content of D00100 (#8000 = –32,768 decimal) to its 32-
bit equivalent (#FFFF 8000 = –32,768 decimal) and writes that result to
D00201 and D00200.
3-12-8 DATA DECODER: MLPX(076)
Purpose Reads the numerical value in the specified digit (or byte) in the source word,
turns ON the corresponding bit in the result word (or 16-word range), and
turns OFF all other bits in the result word (or 16-word range).

Operands S: Source Word
The data in the source word indicates the location of the bit(s) that will be
turned ON.
C: Control Word
The control word specifies whether MLPX(076) will perform a 4-to-16 bit con-
version or an 8-to-256 bit conversion, the number of digits or bytes to be con-
verted, and the starting digit or byte.
