Equating a Name with a Field, Expression, or Command
Displaying Attributes of a Field
You can display the attributes of a field using the Attribute (ATTR) debug
command. The attributes are the size (in bytes) and type of the variable as
recorded in the debug symbol table.

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

Equating a Name with a Field, Expression, or Command
You can use the EQUATE debug command to equate a name with a field,
expression or debug command for shorthand use. You can then use that name
alone or within another expression. If you use it within another expression, the
value of the name is determined before the expression is evaluated. These names
stay active until a debug session ends or a name is removed.
