Use this function to set a offset for the current lcd line. It means that the output on lcd is started away from origin the number of steps given by offset. The function demands the following parameters:

Parameter 1 -> direction of offset [ Horizontal, Vertical ]
Parameter 2 -> offset
Parameter 3 -> line [optional parameter]

Example:

%Format.Offset(Horizontal,-5,1)
ABCDEF

This function call sets a offset of -5 for horizontal output on line 1. If the origin of lcd output is 0,0 (upper left corner of lcd screen) the first 5 characters of "ABCDEF" are truncated. So the single character "F" is displayed on lcd.
