The formulas below show an example of how an array can be used to create and populate an array with a list of solicitor names.
What are parameters in Crystal Reports?
Parameters are used to take user inputs before the report is generated. User has to answer the prompt before the report is generated and the report output depends on the response of the user for the parameter value.

What are formulas in Crystal Reports?
Crystal Reports – Defining Formulas. Formulas are used to insert data in the report that does not exist with any of the objects. If there is a need to perform some calculations or to add specialized data in the report, you can use formulas. Example − (Emp_details.sal) * 0.15.
What determines the shape of a crystal?
A number of variables, such as the size and length of their surfaces (known as ‘faces’) and sides, and the angles between them, define the shapes of crystals. These forms are named for their geometry – for example, the ‘cubic or isometric’ crystal group belongs to crystals centred on cubes.
What is a crystal system in chemistry?
A Crystal System refers to one of the many classes of crystals, space groups, and lattices. In crystallography terms, lattice system and crystal, the system are associated with each other with a slight difference. Based on their point groups crystals and space groups are divided into seven crystal systems.
How is crystal structure obtained?
Crystal Structure is obtained by attaching atoms, groups of atoms or molecules. This structure occurs from the intrinsic nature of the constituent particles to produce symmetric patterns. A small group of a repeating pattern of the atomic structure is known as the unit cell of the structure.
