add data table entry object

Add some sort of? object to an existing app that allows a user to enter up to 100? two-column entries that are stored somewhere for retrieval during the program's existing process.? ? The data in the columns? needs to read? and do an action with it (that process is already done and is not included in this project request).? The storage location for the column data needs to remain simple -- no database or anything that complex because I want the app to remain simple and small.? A? text file is fine because? the data does not need to be encrypted or secured.? The data should be able to be saved so that the user can retrieve it and use it in the app over and over.? Also, they should be allowed to make changes to existing entries that get updated when saved again.? I have an existing application that collects user input on various tabs on the interface.? One of the tabs is to collect "all other" entries.? Currently the user is limited to only a set amount of all other entries because I collect them using single fields.? All of the entries are stored into a dynamic array.? When the user clicks the go button to accomplish what the program is supposed to do with the entries, it reads the entries from the array to process them according to the program's instructions.? I wrote this app. ? What I want to do is change the all other tab to have a grid instead of the individual fields that will allow the user to put in matched pairs of entries? 1 to 100 (not likely that high, but want to allow for that many).? The entries can also be stored in a dynamic array.
