fixed an issue with enum stuff

    %---------

    % call pvs in batch mode with script

    % ADD check that pvs actually exists in system

    [status, result] = system(['pvs -batch -v 3 -l ' function_name '.el']);

    [status, result] = system(['pvs -batch -v 3 -l ' function_name '.el'])

    %objectect.msgbox_scroll(result);

    waitbar(.70,box,'Parsing Results');

    [parsed error] = object.parse_pvs_result(result);

counter_display = [];

enum_array = [];

if size(object.PVS_results(object.page).ce,2) == 0

    counter = ['no counter example generated'];

    counter_display = ['no counter example generated'];

else

    for i = 1:2:size(object.PVS_results(object.page).ce,2)

        % an enumerated type need to do some more work.

        % check if new_value contains any characters [a-zA-z]

        isstring = regexp(char(new_value),'\w','match');

        isstring = regexp(char(new_value),'[a-zA-Z]','match');

        if ~isempty(isstring)

            % value is an alpha string

        else

            % value is numeric

            eval(['value = ' char(new_value) ';']);

            new_value = value;

            new_value = num2str(value);

        end

        % need different string for output vs evaulation
