==Daily summary Log in Cumulus 1==
In the '''Edit''' menu, select '''Dayfile.txt''' screen, for a text editor where you can overwrite entries, delete entire lines, and insert new lines (and then manually type in values for every field). You can scroll left and right between fields, with a header row identifying which field is which, and you can scroll up and down through all the lines. If you know what you want to change (such as replacing a rogue figure), this is a very easy to use editor.
For the daily summary log, the original Cumulus software includes functionality to '''Create Missing''' in its daily summary log editor, which will be described next. This functionality creates an entire missing log line and will insert highs and lows whether they are extremes of source values, or extremes of derived values. This functionality is not designed to work out individual missing extreme figures, only to insert complete missing lines. However, we can workaround that constraint:
*If a required source or derived value is not present in the standard data log lines, Cumulus will write into related dayfile.txt fields zero for values, and "00:00" for time stamps, because it does not understand the concept of "Null".
*Cumulus 1 does not have the functionality to retrospectively calculate derived values when it is reading source values in the standard data log line.
