## Other Forms

GDL forms in this section are those that do not really fit anywhere else.

- Default Display Style
- The Random State
- Debugging Support

UnitTypeProperty: `name-internal` str

Internally used type name.

### Default Display Style

The exact style of display depends on the user interface and on user preferences, but for some games, you may want to encourage a particular style by making it be the default.

GlobalVariable: `unseen-char` str

This variable is a string whose first character will be used to represent unexplored terrain. If the string consists of two characters, the second char will be scattered throughout a field of the first char. Defaults to `""`.

GlobalVariable: `unseen-color` str

This variable is the name of a color that will be used to represent unexplored terrain. Defaults to `""`.

GlobalVariable: `unseen-image-name` str

This variable is the name of an image that will be used to represent unexplored terrain. Defaults to `""`.

GlobalVariable: `grid-color` str

This variable is the name of a color to use to draw the cell-separating grid. Defaults to `""`.

### The Random State

It is useful to be able to restart the random number generator consistently.

GlobalVariable: `random-state` n

This variable is the state of the random number generator. If this is not used, then the initial state of the random number generator will be set in a system-dependent way.

### Debugging Support

Form: `print` value

This form prints to a console or file (depending on the interface) the object value, in GDL syntax.
