Here are some sample 
Format Strings to use as reference when writing your own: 
- %.2f,%.2f,%.2f
 Enters XYZ values using 2 
decimal points of precision and separates the values with commas.
 
 
- %.3f,%.3f,%.3f
 Enters XYZ values using 3 
decimal points of precision and separates the values with commas.
 
 
- %.4f,%.4f,%.4f
 Enters XYZ values using 4 
decimal points of precision and separates the values with commas.
 
 
- %.4f %.4f 
%.4f \n
 Enters XYZ values using 4 
decimal points of precision, separates the values with spaces, and sends a 
carriage return at the end of the string.
 
 
- %.3f,%.3f
 Enters X and Y values (omits 
Z) using 3 decimal points of precision and separates the values with 
commas.
 
 
- %.4f,%.4f,0.0
 Enters X and Y values (enter 
"0.0" for Z) using 4 decimal points of precision and separates the values with 
commas.
 
 
- %.4f\t%.4f\t%.4f
 Enters XYZ values using 4 
decimal points of precision and separates the values with tab 
characters.
 
 
- %.4f\t%.4f\t%.4f\t\n
 Enters XYZ values using 4 
decimal points of precision, separates the values with tab characters, and 
finishes with a final tab and a carriage return.
 
 
- \t\t%.4f\t%.4f\t%.4f\t
 Enters 2 tab characters 
followed by XYZ values using 4 decimal points of precision. The values are 
separated with tab characters, and finish with a final tab. In this example, it 
should be assumed that the program, after accepting the point data, leaves the 
focus in a field other than the "X" field, requiring 2 tabs to get back to the 
"X" field. The final tab would be required to take the focus from the "Z" field 
to an "OK" or "Take Point" button.
 
 
- %.4f\n%.4f\n%.4f\n
 Enters 4 decimal points of 
precision and separates values with a carriage return.
 
 
Here is a sample 
Format String that exports both tip position and stylus orientation 
values: 
- %.4f\t%.4f\t%.4f\t%.4f\t%.4f\t%.4f 
\n
 Enters 
XYZ position and the associated IJK stylus approach vector values using 4 
decimal points of precision, separates the values with tab characters and 
finishes with a carriage return. This is the pattern used by the Excel +ijk 
default format string.
