High Order Language Working Group

High Order Language Working Group is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand High Order Language Working Group rather than just read about it. In short: The High Order Language Working Group (HOLWG) was a working group instrumental in developing the Ada computer programming language. The group was established in 1975 with the goal of establishing a single high-level programming language appropriate for United States Department of Defense (DoD) real-time embedded computer systems.

Key takeaways

High Order Language Working Group belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect High Order Language Working Group to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of High Order Language Working Group from memory before moving on to harder problems.

Reference excerpt

The High Order Language Working Group (HOLWG) was a working group instrumental in developing the Ada computer programming language. The group was established in 1975 with the goal of establishing a single high-level programming language appropriate for United States Department of Defense (DoD) real-time embedded computer systems. Colonel William A. Whitaker chaired the group. The group was centered in the US, but input was solicited from international experts. European experts responded well, which was valuable since language research there, during the prior decade, was more active than in the US. Some highly accomplished academics were paid including Edsger W. Dijkstra, Charles Antony Richard Hoare, and Niklaus Wirth. HOLWG had three objectives:

formulate the requirements for common DoD high order languages; compare those requirements with existing languages; and recommend adoption or implementation of the necessary common languages.

Worked examples

Example 1 — a first encounter with High Order Language Working Group

Start with the simplest possible case. Write down what High Order Language Working Group claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to High Order Language Working Group before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about High Order Language Working Group ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of High Order Language Working Group

In research: High Order Language Working Group appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses High Order Language Working Group in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: High Order Language Working Group is common in secondary-school and first-year university syllabi. It links to neighbouring topics Ada (programming language), United States Department of Defense information technology, Working groups, so understanding it makes those chapters shorter.
In everyday life: Look for High Order Language Working Group outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
