Hello!

In Forms 4.5 I created a Parameter List using

"create_parameter_list(pl_name)"

and filled it up with some values using

"add_parameter(...)".

Now I would like to retrieve the results in a way like this:

    tmp_num := 0;
    tmp_val := 'start';
    par_name := 'par' || to_char(tmp_num);

    while ( tmp_val != '' )
    LOOP

      get_parameter_attr(pl_name, par_name, tmp_out, tmp_val);
      message('OUT: "' || to_char(tmp_out) || '" VAL: "' || tmp_val || '"');
      tmp_num := tmp_num + 1; 
      par_name := 'par' || to_char(tmp_num);

    END LOOP; But I have two problems:

• How do I detect the end of the Parameter List?
• Why does the while-condition "( tmp_val != '' ) doesnt evaluate to TRUE (even not at the beginning)?

Thanks in advance for your help,
Martin
