Shows each symbol or literal. Symbols are shown in the form in which they are defined, either in the name entry of a machine or assembler instruction, or in the operand of an EXTRN or WXTRN instruction. Symbols defined using mixed-case letters are shown in mixed-case letters, unless the FOLD assembler option was specified.

If a symbol name is used as a literal more than once in a program, and the form of the symbol name is coded differently, for example =V(symbol) and =V(SYMBOL), and the symbol is not defined in the program, the symbol is listed in the form of the first reference. In the following example, the assembler lists the symbol name as inPUT, because the third statement is the first occurrence of the symbol, and the symbol was not previously defined.

test     csect
         using      *,15
         la         1,=v(inPUT)        third statement
         la         1,=v(INPUT)
         end

In the following example, the assembler lists the symbol name inPUT, because the third statement defines inPUT as an external symbol. The assembler also lists the symbol name INput, because the fifth statement defines INput as an ordinary symbol.

test     csect
         using      *,15
         la         1,=v(inPUT)        third statement
         la         1,=v(INPUT)
INput    dc         cl4' '             fifth statement
         END

2

Shows, in decimal notation, the byte length of the field represented by the symbol. This field is blank for labeled USINGs (see symbol WA).

3

Shows the hexadecimal address assigned to the symbol or literal, or the hexadecimal value to which the symbol is equated. This field is blank for labeled USING symbols. The Value column can contain the UNDEFINED or QUALIFIER strings, depending on the properties of the symbol.

4

For symbols and literals defined in an executable control section or a dummy section, this field shows the external symbol dictionary ID (ESDID) assigned to the ESD entry for the control section in which the symbol or literal is defined. For external symbols, this field indicates the ESDID assigned to ESD entry for this symbol. For symbols defined in a dummy control section, this field indicates the control section ID assigned to the control section. For symbols defined using the EQU statement, if the operand contains a relocatable expression, this field shows the external symbol dictionary ID of the relocatable expression. Otherwise, it contains the current control section ID.

5

Column title R is an abbreviation for “Relocatability Type”. Symbols fl12nd and WA are absolute symbols and are flagged "A" in the R column. Symbol jix is the result of a complex relocatable expression and is flagged "C" in the R column. Symbol IOerror is relocatable and is not flagged.

6

Indicates the type attribute of the symbol or literal. Refer to "Type attribute (T')" in the HLASM Language Reference for details.

7

Indicates the assembler type of the symbol, including type extensions (if any). Refer to HLASM Language Reference for details.

8

Indicates the program type of the symbol. Refer to HLASM Language Reference for details.

9

Is the statement number in which the symbol or literal was defined.

10

Shows the statement numbers of the statements in which the symbol or literal appears as an operand. Additional indicators are suffixed to statement numbers as follows:

B: The statement contains a branch instruction, and the relocatable symbol is used as the branch-target operand address.
D: The statement contains a DROP instruction, and the symbol is used in the instruction operand.
M: The instruction causes the contents of a register represented by an absolute symbol, or a storage location represented by one or more relocatable symbols, to be modified.
U: The statement contains a USING instruction, and the symbol is used in one of the instruction operands.
X: The statement contains an EX machine instruction, and the symbol in the second operand is the symbolic address of the target instruction.

In the case of a duplicate symbol this column contains the message:

****DUPLICATE****

A symbol name can appear in the cross reference section as both an external symbol name and an ordinary symbol name. In this situation there is no duplication.

The following notes apply to the cross reference section:

Notes:

Cross reference entries for symbols used in a literal refer to the assembled literal in the literal pool. Look up the literals in the cross reference to find where the symbols are used.
A PRINT OFF listing control instruction does not affect the production of the cross reference section of the listing.
In the case of an undefined symbol, the columns Length ( 2 ) and Value ( 3 ) contain the message:
```
****UNDEFINED****
