3. Copy all captured files from both sides into a single directory. (This is not necessary if
both computers are networked and all captured files are accessible to the computer
running the scoring program.) These are identified by [Date] [Time] and [Computer ID].
4. Click on the PC#1 File button.
5. Choose the data file you wish to score from the PC#1 side and click OPEN.
6. Click on the PC#2 File button.
7. Choose the data file you wish to score from the PC#2 side and click OPEN. Be sure the
two files match in [Date], are very close in [Time], and that [Computer ID] matches the
computers used.
8. You may wish to review the captured files in the scroll window to assure that you will be
scoring the correct files. You will notice that some special characters have been inserted
to represent backspaces, line feeds, and carriage returns. They will be restored to their
original character form before giving the file to the score programs for proper evaluation.
9. Click on the OUTPUT FILENAME button.
10. Select either an existing Excel file or type a new filename such as C:\RESULTS.XLS.
Be sure to include the .XLS extension with the file name you type!! Existing Excel files
will not be overwritten, but additional data will be added to them in new rows.
11. Click on SCORE NOW. This will launch the scoring programs.
12. The results of the eight scores will be displayed in the Excel output window. The scores
can now be examined by using Microsoft Excel or a compatible spreadsheet program.
The data from one PC will be in a single row, and data from the other PC in the row
below it.
Note: The analyzer program will filter CR/LF characters (Carriage Return/Line Feed) before
passing data to the scoring programs. This compensates for automatic CR/LF insertions
by some TTYs.
