SIGN(600) converts the 16-bit signed binary number in S to its 32-bit signed
binary equivalent and writes the result in R+1 and R.
The conversion is accomplished by copying the content of S to R and writing
FFFF to R+1 if bit 15 of S is 1 or writing 0000 to R+1 if bit 15 of S is 0.

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.
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).
