The Add Double Integer and Subtract Double Integer
instructions add or subtract two 32-bit integers, and
produce a 32-bit result (OUT).
ENO
In LAD and FBD:
OUT OUT
In STL:
ENO
Error conditions that set ENO = 0: SM1.1 (overflow),
OUT OUT
SM4.3 (run-time), 0006 (indirect address)
These instructions affect the following Special Memory
bits: SM1.0 (zero); SM1.1 (overflow); SM1.2 (negative)
