The data of the program is very important, If you want the program to run correctly, user has to obey some following principles while inputting data in the table.
+ Input the data and its value correctly. E.g: It is impossible to input the depth of borehole by the signs such as 'abc', scale as 'def'....
+ Input enough data for creating a drawing. E.g: The cross must be Horizontal and Vertical .SCALE, the Lithology need have layers.
Notices:
It's not acceptable to have any blank row, the rows below the blank row will not be updated.


In the drawing which is input incorrectly, the data below the blank will not be updated.
+To copy borehole data to a new one, all data rows must be copied.(choose rows from its order).
