What is The Difference Between PL/I And Q, Programming Languages

PL/I is a Procedural Programming Language, while Q is an Interpreted Programming Language

What are Procedural Programming Languages

Procedural (imperative) programming implies specifying the steps that the programs should take to reach to an intended state. A procedure is a group of statements that can be referenced through a procedure call. Procedures help in the reuse of code. Procedural programming makes the programs structured and easily traceable for program flow.

What are Interpreted Programming Languages

An interpreted language is a programming language for which most of its implementations execute instructions directly, without previously compiling a program into machine-language instructions. The interpreter executes the program directly, translating each statement into a sequence of one or more subroutines already compiled into machine code. (Wikipedia)

While PL/I is a Procedural Programming Language, and Q is an Interpreted Programming Language

Let us now look at the difference between the two:

What is PL/I Programming Language – A brief synopsis

It is an imperative computer programming language targeted at scientific and engineering applications. Mainly intended to perform data processing, it also supports structured programming and recursion.

What is Q Programming Language – A brief synopsis

It is called Q for being an equational programming language. It is an interpreted functional language that was designed by Albert Graf at the University of Mainz in Germany. It can be described as a set of equations used to evaluate expressions.
