I am trying to do two simple tasks and I cannot find the answer in help topics.
1) How can I format an entry field in Dialog Sytem to display a zip code with dashes. For example, I am trying to display the zip code 115308020 as 11530-8020. I am able to format amount fields and date fields but I cannot figure out zip code fields
2) Dialog Sytem comes with insert fields as INS1 and INS0. I am trying to give the user the ability to overwrite text on an entry field. For example, on most windows application, users simply hit the "insert" key on their keyboard in order to overwrite text as appose to appending text. But the help topics in Dialog System does not really provide information as to how to use their INS1 and INS0 functions in order to achieve this.
Thanks in advance for your help
