2024.1
Overview of external readers and the Altair Binary Format, the generic ASCII reader, running applications in batch mode, using Tcl/Tk commands, translators, and result math.
Altair Binary Format (ABF) is the standard binary format read by the program. A library called abflib allows you to create files in ABF.
An Altair Binary Format file can include labels and annotations that contain additional information.

Extensions are programs integrated with the application to enhance or extend the user experience.
ABF is organized according to a three-tier system. The format consists of two parts, the header and the data.
The program reads a variety of ASCII and binary formats and have a template-based system that allows you to read formats which are not supported internally. This template-based system uses a language called Import.
ABF and the program use a three-tier system comprised of datatypes, requests, and components. A file that does not contain three tiers cannot be translated into Altair Binary Format unless it is restructured into three tiers.
The ABF library is used to write to Altair Binary Format files. Before you can write to an ABF file, it must first be initialized. Once the file is initialized, you can create and open the file. When you write to an ABF file, the existing file is overwritten without warning.
Once an Altair Binary Format file is created and opened, the structure of the data contained within the file must be specified. The data structure and the data can be specified in one step or the data can be entered after the data structure is specified.
In Altair Binary Format files, data is stored at the component level. The default data format is eight-byte floating point values.
Once the data structure and data for each component have been specified, the ABF library can output the ABF file.
An external reader is usually called several times while importing data. This process allows you to specify what file information you want to access.

Specifies the component to empty.
Empties the currently opened component.
Changes the ABF file header to reflect that an error occurred in translation (making the file unreadable) and imbeds a message in the file which is displayed in the message log.
Changes the ABF file header to reflect that an error occurred in translation (making the file unreadable) and imbeds a message in the file which is displayed in the program's message log.
Returns the name of the currently open component.

Adds a warning to the ABF file which is displayed in the message log.
Outputs the ABF header, which contains information on the structure and content of the file.
Outputs the ABF header, which contains information on the structure and content of the file, and the data itself.
When a data component can be expressed in terms of another, it is unnecessary to include the full set of values for both.
A generic ASCII reader is now available which allows you to bring custom results directly into HyperView. The Altair ASCII format is useful for reading the results of any in-house or propriety codes which are saved in a generic format.
Batch mode allows you perform a series of operations outside the program interface.
External resources can be registered in preference files, session files, or Templex files. If an external resource is registered in a program session, it is automatically registered in the session file when the session is saved.
