What is The Difference Between OPAL And SGML, Programming Languages

OPAL is an Interpreted Programming Language, while SGML is a Markup 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 Markup Languages

A markup language is an artificial language that uses annotations to text that define how the text is to be displayed.

While OPAL is an Interpreted Programming Language, and SGML is a Markup Language

Let us now look at the difference between the two:

What is OPAL Programming Language – A brief synopsis

The name stands for Optimized Applicative Language and is a functional programming language developed at the Technical University of Berlin.

What is SGML Programming Language – A brief synopsis

Standardized General Markup Language (SGML) has descended from IBM’s Generalized Markup Language. It is an ISO standard metalanguage that can define markup languages for documents. It was designed with the intent of sharing machine-readable documents of large projects that had to be retained for long years.
