Always a good warning.

    Procedurename argument
is not semantically the same as
    Procedurename (argument)

However, I disagree with the characterization that it is a 'bug' or
that the results should even be 'unexpected'. The grammatic rules for
calling VB procedures and using parathentheses are very clear. If one
doesn't follow the rules then surprises are to be expected. <g>
