Displaying Attributes of a Field

You can display the attributes of a field using the Attribute (ATTR) command. The attributes are the size (in bytes) and type of the va recorded in the debug symbol table.

Figure 104	shows	some examples of displaying field	attributes based	on
in Figure 105 on		page 212. Additional examples are	also provided in	the
debugger	online	help.

Equating a Name with

You

can

use

the EQUATE debug command to equate
