In the context where an assignment statement is assigning a value
to a shell variable or array index, the += operator can be used to
append to or add to the variable's previous value.
This includes arguments to builtin commands such as \fBdeclare\fP that
accept assignment statements (\fIdeclaration\fP commands).
When += is applied to a variable for which the \fIinteger\fP attribute has been
set, \fIvalue\fP is evaluated as an arithmetic expression and added to the
variable's current value, which is also evaluated.
