This item is tagged for TC3-2008

V7TC2D4 Page 2366, Line 75516, (TC2D3 #75172), Section: 2.9.1 Change:

    If the command name is a special built-in utility, variable
    assignments shall affect the current execution environment.

to:

    If the command name is a special built-in utility, variable
    assignments shall affect the current execution environment
    before the utility is executed and remain in effect when the
    command completes; if an assigned variable is further modified
    by the utility, the modifications made by the utility shall
    persist.

Change V7TC2D4 XCU 2.14, Item 2 (Page 2385, L76309) from:

    2. As described in Section 2.9.1, variable assignments preceding
    the invocation of a special built-in utility remain in effect
    after the built-in completes; this shall not be the case with
    a regular built-in or other utility.

to:

    2. As described in Section 2.9.1, variable assignments preceding
    the invocation of a special built-in utility affect the current
    execution environment; this shall not be the case with a regular
    built-in or other utility.

Change the description of set -a (V7TC2D4 P2409 L77097-77103) from:

    When this option is on, the export attribute shall be set for
    each variable to which an assignment is performed; see XBD
    Section 4.23. If the assignment precedes a utility name in a
    command, the export attribute shall not persist in the current
    execution environment after the utility completes, with the
    exception that preceding one of the special built-in utilities
    causes the export attribute to persist after the built-in has
    completed. If the assignment does not precede a utility name
    in the command, or if the assignment is a result of the operation
    of the getopts or read utilities, the export attribute shall
    persist until the variable is unset.

to:

    Set the export attribute for all variable assignments. When
    this option is on, a variable that is assigned a value (see
    [xref to XBD Section 4.23]), including variables that are
    assigned a value by the getopts, read, or cd utilities, shall
    cause that variable to gain the export attribute. Note: As
    discussed in [xref to XCU 2.9.1], not all variable assignments
    happen in the current execution environment. When an assignment
    happens in a separate execution environment the export attribute
    is still set for the variable, but that does not affect the
    current execution environment.
