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

PL/I is a Procedural Programming Language, while OPAL 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)

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.
