Symbol comparison instructions (double-word, unsigned) compare two values
(constants and/or the contents of specified double-word data) in unsigned 32-bit
binary data and create an ON execution condition when the comparison condi-
tion is true. There are three types of symbol comparison instructions, LD
(LOAD), AND, and OR.
