Field help (DEPPST) 

If the despositor is not entered, the Position field can be accessed. It is used to

specify if the user wishes to see this data

(the depositor) in a row or a column of the grid. This will, upon generation of the graphical representation,

correspond to the abscissa and ordinate

data. The value of the field must start by X for the row

(abscissa or width) and by Y for the column (ordinate or depth).
