Data Attributes
variable_symbol
is a variable symbol that represents the data that possesses the attribute.
literal
is a literal that represents the data that possesses the attribute. A literal cannot
be specified with the operation code attribute or count attribute.
character_string
is a character string that represents the operation code in the operation code
attribute.
Examples:
T'SYMBOL
L'&VAR
K'&PARAM
O'MVC
S'=P'975.32'
The assembler substitutes the value of the attribute for the attribute reference.
| Reference to the count (K'), defined (D'), number (N'), operation code (O'), and
| type (T') attributes can be used only in conditional assembly instructions or within
| macro definitions. The length (L'), integer (I'), and scale (S') attribute references
can be in conditional assembly instructions, machine instructions, assembler
instructions, and the operands of macro instructions.
| Attributes of Symbols and Expressions
| Figure 88 shows attribute references (in the columns) and types of symbols (in the
| rows). Each intersection shows whether (“Yes”) or not (“No”) you can validly apply
| the attribute reference to that symbol type, or (in the case of SET symbols) to the
| value of the symbol.
