Introduction This chapter describes 3B2 scripting features and provides practical examples of scripts and how you can use them.
Scripts can be programmed onto keys, started with a macro, or started automatically when a document is changed, opened or closed. Internal scripting is possible because 3B2 is controlled by macros. Every selection, keystroke, and even mouse movement generates internal macros. The next step after executing a sequence of macros is to include these macros in a script or macro file which can be run with a single command.
A basic script consists of a sequence of macros. As a sequence of consecutive instructions, scripts can be used as an interactive tool between users and 3B2 to control the appearance, behaviour and contents of documents. It is also possible to customise the 3B2 interface using scripts. Scripts test and store working environments and can set, change, transmit and display results.
The core of the language is embedded in 3B2. Similarly, dates, time and the system environment are also embedded. However these similarities to other programming languages should in no way intimidate beginners or novices.
When writing a script you will need to know the appropriate macros to use. This knowledge is gained quickly with practice and experience of writing scripts.
Absolute control of scripts requires good programming abilities and a logical, structured approach to problem solving. However it is important to be aware that there are many complexities involved in scripting which are not immediately obvious. The full power of scripts is limited only by the imagination of the user, much like a programming language. For this reason, we recommend that anything more than simple projects should be undertaken by a competent programmer.
However, there is no such limitation on the use of pre-written scripts. These can easily be started, and can be made to look like extensions to 3B2, for example modifying menus. It also means that the file is portable because regardless of where the file is located, the script will always be inside your document.
The problem with this method is that only the file containing the script will be able to use it. User scripts are probably the most common type of script that you will use. The name of the script does not matter, however it is good idea to give a script a name that describes its function so that it is easily identifiable. These scripts can then be chained together to create a series of scripts.
These are generally located in the 3B2 system directory and read into 3B2 on start-up. If you create your script externally it will be more difficult to develop because of the need to regularly modify and save the script in a text editor such as Notepad and test the results in 3B2. This would result in having to restart 3B2.
However, this can be avoided by using the loadstrs command. One advantage however, is that the script will be truly global and can therefore be accessed by all 3B2 documents. It is more likely that you would develop the script in 3B2 then save it into an external file. In contrast to internal scripts, external string number scripts can not have a regular name, they must have a number. By using defstr and addstr you can either define new strings or overwrite existing strings.
These new strings can describe menus and dialogue boxes for use with your scripts. Further dialogue string examples can be found in the sections on Dialogue boxes. This can be done by putting the script in a user strings file. This file is usually called suser.

Yozshuzuru This in turn provides savings in time and cost. As mentioned previously, they can easily be started, and can be made to look like extensions to 3B2, for example, adding to or changing existing menus. Fully customisable through scripting, 3B2 enables the creation of powerful blackbox publishing applications for printing or electronic distribution. However, there is no such limitation on the use of pre-written scripts.

Automation overview Introduction Some of the main characteristics that have sustained the success of 3B2 have been flexibility, configurability and programmability. These attributes enable 3B2 to automate complex publishing tasks. Advent takes pride in providing the tools to make it easy for users to enhance productivity and control through the implementation of automated publishing solutions. It is with this aim that 3B2 provides a dynamic WYSIWYG scripting environment and a wide range of tools for the automated creation of many document components, for example, multiple indices, tables and the ability to define custom requirements. Template development, consultation and training are all services offered by Advent to either develop entire solutions or aid customers in developing their own. Automation in a publishing environment can be quickly summed up with the following statement: "The composition of an input data stream to an output format based upon a set of predefined rules; without the intervention of an operator or typesetter. It is possible to achieve automation with 3B2 because it is macro driven a macro is a short instruction that performs a function or series of functions.
