What is Programming Language I (PL/I)?

What does PL/I stand for?

Programming Language I (PL/I) is both a procedural and an vital Programming language that cHanged into designed for Engineering, clinical and structures programming, and Business programs. It has been usually utilized by the educational, commercial and industrial sectors seeing that its creation in the Sixties and remains in lively use as of 2011.

PL/1 helps Structured Programming, recursion, linked lists or linked inFormation shape dealing with, Floating-point, fixed-factor and complex Character String and bit String dealing with. The Syntax and words used are similar to English, and the language is properly proper to defining complicated Records formats using a extensive set of features.

What Does Programming Language I Mean?

Programming language 1 turned into born due to the fact IBM wanted to layout a sySTEM that could supersede all the IBM architectures that came before it to turn out to be the commonplace system structure for the commercial enterprise and scientific groups. This became the IBM System 360. Before this, Programmers had to use special languages to program for every Hardware. Similarly, IBM wanted a single commonplace programming language that every one users from any area should use.

PL/1 had the following enormous language capabilities:

• 100% loose form and does no longer have reserved key phrases
• Defines facts types irrespective of hardware
• A Block-orientated programming language that includes begin bLocks, applications and Statements. This structuring approach allows Developers to produce very Modular applications and programs.
• PL/I has manage systems. Structures like SELECT…WHEN…OTHERWISE will allow logical operations, at the same time as DO statements will permit statements to be carried out unconditionally as a minimum once, infiNitely, or at the same time as a condition continues to be authentic or fake depending on the want.
• Supports Data Structures like Arrays, unions, systems, arrays of unions or systems, unions or structures of arrays, and any aggregate of the above.
• Has 4 Storage training: Static, BASED, AUTOMATIC and CONTrollED.
