  • The following expression is accepted:
    (RueckString usual)
    if ( islogic(RueckString) .and. Rueckstring == true)

    The following expression gives the error below
    if ( islogic(RueckString) .and. Rueckstring)

    Error In order for '__Usual.operator &(__Usual, __Usual)' to be applicable as a short circuit operator, its declaring type '__Usual' must define operator true and operator false

    Unfortunately there are many places in our old VO code. Is it necessary to change all places?

    Thank you

  • Arne,

    This problem is fixed in our current development branch.
    If you add a cast to your code then it works in Vulcan as well:
    if ( islogic(RueckString) .and. (Logic) Rueckstring)

    Unfortunately that cast will not work in VO.
