Edit Data Field
You can change the name or the type of a defined data field, or assign it a new value. In order to do this move the input caret to the data field (or just click the data field record in the Data Field Pane to select it), then select the Edit / Edit Data Field menu command.
Of course, you can change the value directly, by entering new data in the main edit window. This command just gives you a convenient way to enter values in a human-friendly form.
You can use the Load/Save Template command in the FlexHEX File menu to load or save your bookmarks and data field definitions.
Comma character is not allowed in data field name.
