address-expression

    Specifies an entity to be examined. With high-level languages,
    this is typically the name of a variable and can include a path
    name to specify the variable uniquely. More generally, an address
    expression can also be a memory address or a register and can
    be composed of numbers (offsets) and symbols, as well as one or
    more operators, operands, or delimiters. For information about
    the debugger symbols for the registers and about the operators
    you can use in address expressions, type Help Built_in_Symbols or
    Help Address_Expressions.

    If you specify the name of an aggregate variable (a composite
    data structure such as an array or record structure) the debugger
    displays the values of all elements. For an array, the display
    shows the subscript (index) and value of each array element. For
    a record, the display shows the name and value of each record
    component.

    To specify an individual array element, array slice, or record
    component, follow the syntax of the current language.

    If you specify a range of entities, the value of the address
    expression that denotes the first entity in the range must
    be less than the value of the address expression that denotes
    the last entity in the range. The debugger displays the entity
    specified by the first address expression, the logical successor
    of that address expression, the next logical successor, and so
    on, until it displays the entity specified by the last address
    expression. You can specify a list of ranges by separating ranges
    with a comma.
