Data analysis is made up of three main stages:
i) Processing of Downloaded Data,
ii) Correction of corrupted lines (if any),
iii) Report Generation.
At this stage files can be added or removed using the corresponding buttons.
Clicking on Process Files proceeds with the analysis.
6.1.4i File Processing
Upon processing the data from each file will be read and checked for corruption, if detected a new screen
will appear to deal with the corrupt line. Our example download has one corrupt line, shortly after clicking
process files the corruption screen appears to deal with this corrupt line.
6.1.4ii Corruption Correction
The corruption screen appears when the first instance of corruption is detected.

As can be seen it is made up of six main caption boxes:
1) Warning caption - confirming that your download files will not be altered.
2) Download file being read from.
3) Valid lines already read.
4) The original corrupted line contained in the file.
5) The correction attempted by the program - this is also where you can make corrections.
6) A sample line for you to base your corrections on.
Along with five user interface buttons:
1) Use >> is enabled only if the corrected line is valid, if clicked it substitutes the corrected line for the cor-
rupt one.
2) Delete >> ignores the corrupt line, allowing the user to produce a report without correcting this line.
3) Skip >> keeps the corrupt line, preventing the user from generating a report.
4) Skip all >> same as the above but for all corrupt lines encountered
5) << Quit stops corruption analysis returning to main processing screen.
In our example the corrupted line is on device 13 (D:0013).
Comparing our original corrupted line with the sample line at the bottom of the screen shot we can see that
the problem is due to the missing hyphens between the T: and S:. The software has detected this and in-
serted the required number of hyphens and spaces. It has also checked that the now corrected line has
passed all the required validity checks, indicated by the fact that the Use >> button is enabled.
All we need to do is check that the important details such as device number, and signal strength have not
been changed.
