&                Substitute operator                           Macro operator

  &name
  or
  &name&
  or
  name&

    Substitutes actual value of macro parameter name.

    The & character has a special meaning when used with macro parameters.
    In general, & separates a dummy argument name from the surrounding
    text, so Turbo Assembler can recognize it for substitution.

    Example:    MACRO mac2 foo
                  foo&sym:
                  DB "We're in O&foo&o"
                ENDM

                Invoking the macro with: mac2 <hi>
                will generate:

                hisym:
                  DB "We're in Ohio"


    ■ Outside quoted strings, the & serves only as a general separator.
    ■ Inside quoted strings, and after a semicolon that's not in a quoted
      string in Ideal mode, & must precede a dummy argument for it to be
      recognized.
    ■ Turbo Assembler removes one & from any group of &s during a macro
      expansion. This makes it possible to place macro definitions
      requiring & characters inside other macro definitions.
