User-defined Data Fields
Data field is simply a file area to which the user assigned a type and, optionally, a name. If we talk about a program, we would call that object a variable, but for a static file this term does not seem proper.
Although we still can change a data field value by typing new data in the FlexHEX edit window, the Edit Data Fieldcommand provides a more convenient way.
The Data Field pane lists all defined data fields and lets you navigate them quickly.
