functions

. edi t_day: A number showing the day of the checksheet being edited.
. date: The date of the checksheet (year and month).

. inher i t_da te: The date from which the checksheet was copied, if the new
flag is true.

. number_checksheet_yows: The number of rows in the checksheet.

. data: An aTTay of checksheet rows.

typedef struct row_struct {

intid;
introw_type;
char *forrnula;

Where:

. rd_only _f lag: A flag indicating that the user may not edit the row.

. i d: The ID of the row, from the Checksheet fonnat file.

. row_type: A number indicating the type of the row.

. formula: A character string containing the formula from the Checksheet formal
file.

. name: The name, or printed title, of the row.

. day_value: An array of daily numbers for the row, one for each day in the
sheet.

. currently_edited: A flag indicating that the row has been edited.

The GUl manipulates a loaded checksheet directly. The sheet is loaded by a call to the
DMI function LoadChecksheet () and archived by the function SaveCheck~
sheet ( ) .

LoadChecksheet () first calls CreateChecksheet () which reads the
checksheet fonnat file and initializes the structures which comprise the Checksheet.
The result is a set of data structures that have the appropriate number of rows, each of
the correct type and with proper writability, but which lack any data values.

LoadChecksheet () then checks to see if the requested sheet is saved in the data-
base. If it is not, it creates a blank sheet and selS the new flag to I. Otherwise, the
application reads the values from the database, using the function LoadCheck-
sheetFromDate ( ), and sets the new flag to O.

Several DMI routines are used for the data retrieval, all of which fetch values for rows
in the sheet. Unlike the Water Infonnation Sheet, the Checksheet has no header infor-
mation. Rows of type flow are loaded by the function SQLLoadCsF1owRow ().
