Most of these instructions are shown with a symbol and options. When the op-
tions are not included, the instructions will handle unsigned one-word data.
Symbol
= (Equal)
< > (Not equal)
< (Less than)
<= (Less than or equal)
> (Greater than)
>= (Greater than or equal)
Unsigned input comparison instructions (i.e., instructions without the S option)
can handle unsigned binary or BCD data. Signed input comparison instructions
(i.e., instructions with the S option) can handle signed binary data. For informa-
tion concerning signed binary data, refer to 4-13 Data Formats .
The following table shows the function codes, mnemonics, and names of all of
the input comparison instructions. For details, refer to 5-16-7 Input Comparison
Instructions (300 to 328) .

With the earlier comparison instructions, CMP(020) and CMPL(021), the com-
parison result was output to the Greater Than Flag (A50005), Equals Flag
(A50006), and Less Than Flag (A50007), and those flags then had to serve as
the input condition for subsequent processing in accordance with the compari-
son result.
