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).
● Comparison flags (system relays SRA to SRC) are processed as follows.
SRA SRB SRC
> = <
[S1] < [S2] OFF OFF ON
[S1] = [S2] OFF ON OFF
[S1] > [S2] ON OFF OFF
● If the numbers of characters to be compared are different, they are processed as follows.
[S1] [S2]
"ABCDE" = "ABCDE"
“ABCD” < "ABCDE"
"B" > "ABCDE"
