Applicable Program Areas
Operand Specifications
Note
R and R+1 must be in the same data area.
Description
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.
