Attributes are used to control the appearance and placement of a tile definition in a DCL file.
Within the curly braces of a tile definition, you specify attributes and assign them values using the following form:
attribute=value;
An equal sign ( = ) separates the attribute from the value, and a semicolon ( ; ) ends the assignment statement.
For example, the key attribute defines the name by which a program can refer to a tile, and the label attribute defines the text displayed within the tile.
