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

Both Oberon and PL/I are Procedural Programming Languages
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.

Since Oberon and, are both Procedural Programming Languages
Let us now look at the difference between the two:
What is Oberon Programming Language – A brief synopsis
Niklaus Wirth, the man behind Pascal and Modula came up with Oberon in 1986. It was designed as a part of the Oberon operating system. It is similar to Modula-2 but smaller than it.
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.
