3. This form displays the Parameter details. To add a new Parameter, click the 'Add' button (A), and a blank row will appear.
4. Enter the Parameter name in the box (C).
5. Pick the Parameter Type from the drop-down (D).
6. Optionally enter a Formula in the box (E). When this entry is left empty, the user is responsible to assign a value to the parameter elsewhere in the system. An expression defined in the formula defines a substitution expression that will be calculated on the fly, whenever encountered, and may receive different values if it includes a random number generator. The formula is a general expression, yet it is restricted by the parameter type and validation rules.
7. Optionally Pick a Validation Rule from the drop-down (F), which will verify the output type of the Formula. If you do not pick a validation rule, it will be defined by default by the system according to the parameter type.
8. Optionally Enter the Validation Rule Parameters in the box (G). A Validation Rule will define the range of values the parameter may have within brackets. If you do not pick a validation rule, it will be defined by default by the system according to the parameter type.7
9. Close the form or move to the next record to save the entry. This will trigger validity checking of the data entered and if no error message is displayed, then the data has been saved to memory. Note that the information is not yet saved to a file.

Note that the parameters form can accessed from other forms by double clicking a field that requires a parameter. This allows creating parameters on the fly while working from another form.
