Relational condition format

Two formats for the relational condition can be used:


>>-(p1,m1,BI,--+-ALL-----+--,--mask--)-------------------------><
               +-SOME----+               
               +-NONE----+               
               +-NOTALL--+               
               +-NOTSOME-+               
               +-NOTNONE-+               
               +-BO------+               
               +-BM------+               
               +-BZ------+               
               +-BNO-----+               
               +-BNM-----+               
               '-BNZ-----'

Or, if the FORMAT=BI operand is used:


>>-(p1,m1,--+-----+--+-ALL-----+--,--mask--)-------------------><
            '-BI,-'  +-SOME----+               
                     +-NONE----+               
                     +-NOTALL--+               
                     +-NOTSOME-+               
                     +-NOTNONE-+               
                     +-BO------+               
                     +-BM------+               
                     +-BZ------+               
                     +-BNO-----+               
                     +-BNM-----+               
                     '-BNZ-----'

Bit operators describe the input field to mask relationship to be tested as follows:

ALL or BO: All mask bits are on in the input field
SOME or BM: Some, but not all mask bits are on in the input field
NONE or BZ: No mask bits are on in the input field
NOTALL or BNO: Some or no mask bits are on in the input field
NOTSOME or BNM: All or no mask bits are on in the input field
NOTNONE or BNZ: All or some mask bits are on in the input field

The first set of operators (ALL, SOME, and so on) are intended for those who like meaningful mnemonics. The second set of operators (BO, BM, and so on) are intended for those familiar with the conditions associated with the Test Under Mask (TM) instruction.
