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.
External Resources
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.

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.
- Extensions
  Extensions are programs integrated with the application to enhance or extend the user experience.
- External Readers and Altair Binary Format
  Altair Binary Format (ABF) is the standard binary format read by the program. A library called abflib allows you to create files in ABF.
- Generic ASCII Reader
  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
  Batch mode allows you perform a series of operations outside the program interface.
- External Resources
  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.

  - Import Templates
    Import templates are files that contain instructions for reading plot data files.
    - Import Language
      Import is an interpretive computer language designed specifically to create templates for reading plottable data files, such as XY data or time-histories. It is not a general purpose language, like C or BASIC. Import focuses on reading data files in the fastest most reliable manner.
    - Import Template Structure
      Each template typically consists of four sections or blocks.
    - Read Import Data
      Import templates are based on sequential access. All commands that read information, with the exception of integer variables, transfer data into a list or an array.
    - Data Flow Control
      Import contains provisions for jumping ahead in a file and then backing up (using rewind).
    - Errors and Error Handling
      Many import commands can result in a failure condition. This means that the template cannot complete the execution of a command in a meaningful fashion.
    - Conditional Execution
      The only time that a failure condition does not terminate execution is if it occurs in an if block.
    - Loops
      Besides conditional execution, Import also supports iteration.
    - Variables and Integer Math
      Integer variables can be declared anywhere in the global block of a template by using the int directive.
