What is The Difference Between Forth And OPAL, Programming Languages

Both Forth and OPAL are Interpreted Programming Languages

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)

Since Forth and, are both Interpreted Programming Languages

Let us now look at the difference between the two:

What is Forth Programming Language – A brief synopsis

It is a structured imperative programming language, which bases its implementation on stacks. It supports an interactive execution of commands as well as the compilation of sequences of commands.
