|3. Menu headings|
The [VALUES] menu is used to change the input parameters used in the program simulations. Five sets of inputs are required: collection; processing; wastage; distribution; extent necessary; and recipients. Within [VALUES], it is possible to modify the inputs used to reflect a particular intervention. [VALUES] can be selected either by using the mouse, or by pressing the [Alt] and V keys together. For illustration, the Blood Distribution input screen is shown below.
Options within [VALUES] can be selected using the mouse; or by using the down arrow key to move the highlighted bar down to the option required, and then pressing [Enter]. Once an option within [VALUES] has been selected, a list of inputs will be shown. The input values shown can be selected and altered either by using the mouse, or by using the [Tab] key or the [Tab] and [Shift] keys together to move between different entry fields. By clicking the OK button or pressing [Enter], the user can exit the option and return to the [VALUES] menu. If no further changes within this option are made, the input values shown at this point will be used in any subsequent calculations. More details about [VALUES] are given in Section 4.
