Map listing

The map listing is requested with the DATA-ALLOCATION-MAP option of the MODIFY-LISTING-PROPERTIES statement. It provides information on all the symbolic addresses used in the program (names of variables and functions).

Explanation

name

Name of the symbolic address.

stcl

storage class: Storage class of the symbolic address.
The following specifiers are used

auto	Variables at block level, excluding static variables
extern	External variables and functions that are defined in a different module
member	Elements of classes, structures or unions Enumeration values
param	Function parameters
reg	Variables declared with the keyword register
static	Static variables at block level, i.e. that are valid at block level
statmem	Static element of a class
typedef	typedef Name
nospec	No storage class was specified

type

Data type of the symbolic address (in a separate line under the storage class).
Most entries are obvious. Special values are:

ass_proc	assignment Operator
bit	bitfield
entry_var	function
enum	enumeration type
enum_val	enumeration value
lab_const	label
mem_pointer	pointer to member
opr_func	operator function
tmpl	Template
tmpl_inst	Template Instanz
tmpl_par_cl	Template Parameter

size

Size of the variable in memory (in bytes).

slice

A slice is an area (code or data fragment) with a length of 4096 bytes that can be addressed via a base register.

The digit specifies in which slice of the data module the variable is located.

offs

Relative address within a slice (decimal).

xoffs

Relative address within a slice (hexadecimal).

enuval

For members of an enumeration type (enum), enuval specifies the value of the member.

stroffs

Byte position of the symbolic address within a structure (decimal).

xstroffs

Byte position of the symbolic address within a structure (hexadecimal).
