To view the data file supplied with the project, load it into Data File Editor:
Note that the File Details section is populated with values; these are taken from the file header of the .dat file.
datavseq.dat is opened in Shared mode and its contents are displayed. In Shared mode, the file is opened with a file locking status of shared, allowing other users to open the file in Shared mode.
Each record is unformatted; that is, it is shown as one continuous line of text. Records are easier to view and edit if they are formatted; for that, you need to create a record layout within a structure file, then apply it to the data file.
