13.3.1 General Use of Windows

Windows can be moved around the screen by clicking the left mouse button on the border and, keeping the button pressed in, the outline of the window can be moved to a new position.

A window which is behind another window can be 'brought to the front' by clicking on the grey band at the top of the window.

The small button in the top left hand corner of the window will 'shrink' the window, this is known as iconising. To do this press the button and select Close from the displayed menu. The window will become an icon at the bottom of the screen, double clicking the left mouse button on the icon will re-open the window.

Message boxes for information or asking for confirmation of an action are displayed on the screen, these must be acknowledged (usually by pressing OK or Cancel) before you can continue.

To select options from the menu, type the number of the desired menu option followed by <return>.

Table of Contents

13.3.2 Main Menu

Each user will have a menu which contains a list of the facilities which they are authorised to use. This menu will be presented to you after logging onto the system.

To select options from the menu enter the required number of the option and press <return>.

The current case, case type, database being used and your username are displayed on the screen.

13.3.3 Form Function Keys

The following function keys are common to all screens in the application:

F1	No function.
F2 'List'	When a user is to enter one value from a set, this key will display a list of the permitted values.
F3 'Accept'	This will have two uses:
	If the form is displaying a list of information, the Accept key will indicate that the user has selected the entry shown by the cursor.
	If the form is a data entry form, the Accept key indicates that the user has finished with the form, and the database should be updated. The data is validated before any changes are made to the database, and if errors are found, the database is not updated, an error message will be displayed on the error line and the cursor is placed in the field containing the invalid data.
F4 'Quit'	This allows a user to leave a form without changing the database. Any data entered in fields will be abandoned.
F5 'Insert'	Allows a user to insert a new entry into a scrolling list.
F6 'Delete'	Allows a user to delete an entry from a scrolling list.
F7 'Next'	Display the next page of entries in a scrolling list.
F8 'Previous'	Display the previous page of entries in a scrolling list.

Accessing the Mapbase by Using the Street Gazetteer Forms

Several NAP, Reports, Survey and Title options (such as Creating a Provisional Ident, View Area of Map, Print Map Section, Create a Survey, Create a Report, Position Report Marker etc) require the use of the Street Gazetteer Forms. Use of these forms is described below.

On entry to the Street Gazetteer (by selecting on one of the relevant options) a list of selection criteria are displayed at the top of the form.

Move the highlight along the menu line using the arrow keys, a description of the highlighted option is displayed. Select one of the options by highlighting it and pressing the <return> key. Select one of: -

Address	This option displays a form which allows you to select a section of the map using the Street Gazetteer.
Title	This option displays a form which allows you to select a title number or case number.
Map Details	This option displays a form which allows you to select a section of the map using either a Map Name or Grid Reference.
Version of Map	This option displays a form which allows you to select a section of the map using a Map Name followed by a selection of a version of that map.

Selection by Address

Once Address has been selected from the menu a form is displayed which allows you to select from the Street Gazetteer.

Searches can be made using complete fields or by using search criteria. The latter is known as 'query by example'. You can use relational, range, alternation and wildcard symbols as follows: -

Use Relational and range operators to search for values that lie in a specific range.
Use Wildcard characters to search for character strings that match a specific pattern.
Use an Alternation operator to search for alternative values.

The table below lists the operators, their names and the types of fields you can use them with:

Operator	Name	Use with field type
=	Equal to	all
>	Greater than	all
<	Less than	all
>=	Greater than or equal to	all
<=	Less than or equal to	all
<>	Not equal to	all
*	Wildcard	character
?	Wildcard	character
:	Range	all
..	Range	Date and time
½	Alternation	all

Normally you do not need to enter '=' except in the following two situations: -

You can search for entries in the database that contain a NULL or blank field by entering an equal sign by itself in the display field.
You can search for entries in the database that contain an asterisk '*' by entering an equal sign followed by an asterisk in the display field. This is because the asterisk is itself a query operator.

Here are some examples of using operators: -

* This means search for any character or number of characters.

E.g. 'New*' will attempt to match with anything beginning with 'New'.

> E.g. '>10' will retrieve all numbers greater than '10' in a number field.

E.g. '>MAIN' will retrieve all character strings alphabetised after 'MAIN' in a character field.

? This means replace a single character e.g. 'NEW?Y' would return any five character word which starts with 'NEW' and ends in 'Y' such as 'NEWBY' or 'NEWRY'. 'NEW??Y' would return any six character word which starts with 'NEW' and ends in 'Y' such as 'NEWSBY' or 'NEWRAY'.

| Use this to search for alternative values in a field

E.g. 'MULBERRY| RUMBLINGWELL' will retrieve entries with either of these character strings.

: Use this to search for values that lie between one value and another in a field e.g. '101:115' will search for all entries within this number range. You can also use the range operator in a character field e.g. 'MULBERRY:RUMBLINGWELL' will retrieve entries that alphabetically fall within these character strings. You can also use the range operator in a character field e.g.'1/12/94:20/1/95' will search for all entries with dates between these values. You can use this in the 'Search Reports' form to search for reports between set dates.

.. This is also a range operator but is used in date (and time) fields to avoid ambiguity with the colon separator used between hours, minutes and seconds e.g. '1/12/94..20/1/95' will search for all entries with dates between these values. You can use this in the 'Search Reports' form to search for reports between set dates. You can also use e.g. '>1/12/94' to search for all reports after a set date, etc.

Once selection details have been entered <F3> will begin a search of the Street Gazetteer. The maximum number of matches allowed is 40, if more than 40 addresses match the details entered then an error message is displayed and you will have to make your selection details more specific.

If no addresses match the selection details then a message is displayed.

If more than one address matches the selection details entered then a second form will be displayed which shows a list of all matching addresses. Move the down using the arrow keys and press <F3> to select the required address. The Eastings and Northings are displayed along with a default size (which can be changed if required).

If a search is taking too long you can cancel it by pressing <Control> and <C> at the same time.

Selection by Title
Once Title has been selected from the menu a form is displayed which allows you to enter either a title number or a case number. Enter either of these and press <F3> to perform the function of the screen (e.g. select Provisional Extent of an Index).

Selection by Map Details
Once Map Details has been selected from the menu a form is displayed which has fields for Map Name, Eastings, Northings and Size.

To select by Map Name, enter a name or press <F2> and choose from the list displayed. Once a selection has been made the Eastings, Northings of the centre of the map and the Size (screen side width of area of map) are displayed.

To select by Grid Reference, enter an Eastings and Northings, the Map Name and Size are displayed.

Press <F3> to accept selection.

Selection by Version of Map

This selection displays a form which prompts for a Map Name followed by a map version selection. This option should be used in the 'Miscellaneous Prints from the Mapbase' dialogues.

Enter a name or press <F2> and choose from the list displayed. Once a selection has been made the storage scale, survey date, origin x, origin y, county, date amended, date imported, map text and status information is displayed for each version of the map held on the database.

If more than one version of the map exists you can use the arrow keys to move to the required version.

Press <F3> to accept selection.
