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. They can be used as fast access codes to any of 3B2's functions. 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. Creating a script is straightforward, making full use of 3B2's normal editing features. 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.
In addition to 3B2's own internal scripting language, 3B2 also includes full support for XPath , Perl scripts and Perl mini scripts. Internal scripts are set in a normal text stream within a 3B2 document and appended with the. By creating a script within your document, you will easily be able to develop and test the script. 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. External String Number Scripts are scripts set into an external strings file, using a defined set of user string numbers. 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. When you have developed a script you may decide that you wish to make it available to other documents. This can be done by putting the script in a user strings file.
This file is usually called suser. See the 'shelp lang. For more information see Making Scripts available to other documents. You can specify an alternate name for user file s by using the command line option '-u: filename' in your 3B2 start-up file, startdos. You will find the full list of command line options in the shelp.
When you have developed a script you may want to make it available to other documents, or even share it with other 3B2 users. Internal scripts are those defined within a document that exist within a 3B2 text stream, and are executed with the trun macro followed by a string containing the name of the text tag.
They are accessible only by the document they are in. External scripts are defined within one of 3B2's string files, exist within a numbered string and are executed with the trun macro followed by the string number. External scripts are accessible by any document. Converting an internal script to a form in which it can be added to your suser.
This is done using the tsave macro with a. You should be aware of some small differences between fdt data and ts data:. If you open a 3B2 document. To convert an internal 3B2 file to an external strings file you must remove the fdt data. This can be achieved using a search and replace routine. It is also necessary to add the string info, i. It is then possible to add your script as a strings file to suser.
These are ignored by the fdt reader but not by the string reader and must be removed. The conversion process is best illustrated by example. Suppose that the text stream ' xedit ' contained the following script:. The tsave "xedit. The file would contain the following lines:. Following the above guidelines, the header line can be changed to a string header, and the last line removed to leave:.
This is now in the right form for the user strings file. To start the script, the macro would now be trun instead of trun "xedit".
You should also be aware that, in this particular example, scripts which simply use defstr and addstr to define what appears in a dialogue box or menu but actually do nothing else could be translated more severely, so that the string in your user file would simply hold the dialogue box or menu definition, for example:.
A number of user-written scripts, many of them with comment lines, are included in the sscr. The sscr. Advent Publishing Systems is pleased to make these available with 3B2 but cannot accept any responsibility for their reliability or otherwise support the features provided using scripts.
Please note that all strings from these files are loaded automatically if the file exists in your 3B2 program directory. As you become familiar with 3B2's scripting language you will build up a library of useful routines which can be re-used in other projects.
To see scripts that are already set-up in 3B2 open the sscrwin. The range of user string numbers available to the user is detailed in the table below:. Reserved USER strings in suser. Reserved USER strings in suser2. Reserved USER strings in suser3. Reserved for Advent strings in this file. Reserved for implementation specific scripts in sscr. Reserved for SGML strings in ssgmluk. Below is a list of scripts in the strings file stuk.
Search and replace script. Builds URI from script variables that were filled in from dialogue box Additionally the script uses the variables from string Mini-script to display showstring counters in units.
Script called from eprint macro. Script to run the Showstring Analysis. Stream Editor — Modeless dialogue box. Format Log Navigation — Modeless dialogue box. Any 3B2 document can have a start-up script known as an autoexec auto-execute. An autoexec runs automatically when the document is opened, unless otherwise specified in the Open document dialogue box.
An autoexec can be used to set-up documents, for example graphic preferences and file specific key assignments or to provide specific special features. The start-up script is simply a text stream called autoexec with the file extension.
In the same way that an autoexec is launched when a file is opened, the autoexit script will be run automatically when a file is closed enabling various actions to take place before a file is truly closed. One such use could be to save the values of the variables within a file. By default, the autoexec script will be run when a file is closed.

In Arbortext APP, variables are named areas of memory used to store a sequence of characters and during the execution of a Arbortext APP session, numbers, strings, or arrays can be stored in variables and used in future computations. The names given to variables are case sensitive. In order to use the variable again the name has to be exact. Variables can be used across documents as they are retained by Arbortext APP and are only reset when the application is closed down. All open documents in one Arbortext APP session can effectively share the same variables. There are numerous kinds of variables in Arbortext APP, with varying syntax, which can be manipulated and used throughout the application.

The software contains an automated publishing engine that can manually or automatically produce Postscript and PDF documents with complex page layouts. Its rules-based engine allows the stylesheet builder to automate demanding page make-up tasks and run them in a 'lights out' server mode. APP 'templates' are stylesheets that comprise page layouts, text formatting styles and scripting. Scripting is used to automate and apply conditions to the publishing process. Traditionally this was done using ' macros ', which are low-level system commands. When using XML, a template can employ XPath or match-statement contexts to specify the exact conditions to which style is applied through the parser.
