Note:
1. Only in character relations.
2. Only in arithmetic relations.
The value of an attribute for an ordinary symbol specified in an attribute reference
comes from the item named by the symbol. The symbol must appear in the name
field of an assembler or machine instruction, or in the operand field of an EXTRN or
WXTRN instruction.
The value of an attribute reference to an expression is the value of that attribute
reference to its leftmost term.
Notes:
1. You cannot refer to the names of instructions generated by conditional
assembly substitution or macro generation until the instruction is generated.
2. If you use a symbol qualifier to qualify an ordinary symbol in an attribute
reference, the qualifier is ignored.
