The tables at the end of a listing file list the macros, structures, unions, records, segments, groups, and symbols that appear in a source file. These tables are not printed in the sample listing, but this section summarizes the information.
Lists all macros in the main file or the include files. Differentiates between macro functions and macro procedures.
Provides the size in bytes of the structure or union and the offset of each field. The type of each field is also given.
“Width” gives the number of bits of the entire record. “Shift” provides the offset in bits from the low-order bit of the record to the low-order bit of the field. “Width” for fields gives the number of bits in the field. “Mask” gives the maximum value of the field, expressed in hexadecimal notation. “Initial” gives the initial value supplied for the field.
The “Size” column in this table gives the size of the TYPEDEF type in bytes, and the “Attr” column gives the base type for the TYPEDEF definition.
“Size” specifies whether the segment is 16 bit or 32 bit. “Length” gives the size of the segment in bytes. “Align” gives the segment alignment (WORD, PARA, and so on). “Combine” gives the combine type (Public, Stack, etc.). “Class” gives the segment's class (DATA, STACK, CODE, etc.).
Procedures, Parameters, and Locals
Gives the types and offsets from BP of all parameters and locals defined in each procedure, as well as the size and memory location of each procedure.
All symbols (except names for macros, structures, unions, records, and segments) are listed in a symbol table at the end of the listing. The “Name” column lists the names in alphabetical order. The “Type” column lists each symbol's type.
The length of a multiple-element variable, such as an array or string, is the length of a single element, not the length of the entire variable.
If the symbol represents an absolute value defined with an EQU or equal-sign (=) directive, the “Value” column shows the symbol's value. The value may be another symbol, a string, or a constant numeric value (in hexadecimal), depending on the type. If the symbol represents a variable or label, the “Value” column shows the symbol's hexadecimal offset from the beginning of the segment in which it is defined.
The “Attr” column shows the attributes of the symbol. The attributes include the name of the segment (if any) in which the symbol is defined, the scope of the symbol, and the code length. A symbol's scope is given only if the symbol is defined using the EXTERN and PUBLIC directives. The scope can be external, global, or communal. The “Attr” column is blank if the symbol has no attribute.
