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

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

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)

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.

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

Let us now look at the difference between the two:

What is Haskell Programming Language – A brief synopsis

Named in honor of Haskell Curry, a logician, Haskell is a standardized purely functional language. It supports pattern matching, definable operators, single assignment, algebraic data types and recursive functions.

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.
