DCL Tile Attributes

This tutorial will give you a detailed explanation of all attributes used in the design
and implementation of dialogue boxes used within AutoCAD/AutoLisp.
I have provided a sample dialogue image of each of the various aspects of attributes,
and the sample DCL Coding that was used to create the dialogue. The sample AutoLisp
coding required to display each dialogue can be found in the downloadable tutorial.

Attributes in DCL define the layout and functionality of tiles. If you are familiar
with Visual Basic, you will find that they are very similar to properties.
DCL Attributes consist of a name and a value.

Note: The value of certain attributes can change at run-time, with user input or
'set_tile' calls.

The value of a tile's attribute must be one of the following type:

Integer

• Numeric Values (integer or real number) that represent
  distances such as width, or height of a tile.

Real Number

• A fractional real number must have a leading digit.
  e.g. 0.1 not .1.

Quoted String

• A quoted string consists of text enclosed in quotation
  marks (" "). Attribute values are case sensitive. "RB1" is
  not the same as "rb1".

Reserved Word

• A reserved word is an identifier made up of alphanumeric
  characters, beginning with a letter. e.g. true or false.
  Reserved words are case sensitive: True does not equal true.
