+, ++, +++ (p. 325)

Problem Description

The description of +, ++, and +++ does not mention the possibility of abnornal termination of the evaluation of the variable {\tt +}. Are the values associated with {\tt ++}, and {\tt +++} are updated?

Proposal (UPDATE)

If the evaluation of the variable {\tt +} is aborted for some reason, then the values associated with {\tt ++}, and {\tt +++} are updated.

Rationale

This clarification is primarily to establish the contents of these variables in all cases.

Current Practice

VAX Lisp updates the values.
