Outline of operation
● This instruction compares the string specified by [S1] and the string specified by [S2]. The
comparison result is output to the system relays SRA to SRC (assessment flags for the
comparison instruction).
● The size of the storage area is not included in the judgment conditions.
● Comparison flags (system relays SRA to SRC) are operated as follows.
[S1] < [S2]
[S1] = [S2]
[S1] > [S2]
● If the numbers of characters to be compared are different, they are processed as follows.
"ABCDE"
"ABCD"
