a positive expression.

Notes:     The Addition operator ('+') can be used to add an
integer number to a relocatable memory operand.  Only
one expression can not be relocatable memory operand.
Both expressions can be integer values.

The Unary Plus has a higher precedence then the Addition
operator.  See 'Operator Precedence' for the order of
