Symbol comparison instructions (double-word, signed) compare two
values (constants and/or the contents of specified double-word data) in
signed 32-bit binary (8-digit hexadecimal) and create an ON execution
condition when the comparison condition is true. There are three types
of symbol comparison instructions, LD (LOAD), AND, and OR.
Time comparison instructions compare two BCD time values and create
an ON execution condition when the comparison condition is true.
There are three types of time comparison instructions, LD (LOAD),
AND, and OR. Time values (year, month, day, hour, minute, and second)
can be masked/unmasked in the comparison so it is easy to create cal-
endar timer functions.
