Any Address or Data Register
Any source and destination registers, respectively.
Index Register—An, Dn, or suppressed.
Positive Infinity
Operand Data Format: Byte (B), Word (W), Long (L), Single (S), Double (D), Extended (X), or
Packed (P).
Specifies a signed integer data type (twos complement) of byte, word, or long word.
Double-precision real data format (64 bits).
A twos complement signed integer (–64 to +17) specifying a number’s format to be stored in the
packed decimal format.
Packed BCD real data format (96 bits, 12 bytes).
Single-precision real data format (32 bits).
Extended-precision real data format (96 bits, 16 bits unused).
Negative Infinity
Immediate data following the instruction word(s).
Identifies an indirect address in a register.
Identifies an indirect address in memory.
