>>-IF--(compare instruction,parm1,condition,parm2)------------->< Option C needs all four parameters. Any compare instruction is valid. However, with a compare instruction, the condition mnemonic appears between parm1 and parm2, instead of after both of them as in option B. In all cases, parm1 and parm2 must agree, as if you were writing the instruction in assembler language. The condition parameter is either condition mnemonic from Table 1, or a numeric condition code mask. This example of option C:
produces:
Option C also provides for three-operand compare instructions.
An example is:
In all option C formats, the instruction is coded first, followed by the appropriate operands in the same order as used in open code, with the condition code mask operand in the next to last position. |
