Stack-based programming?

[Campbell Ritchie]

Did you know that you can program things which live on a stack?  Did you know you can pass instructions and have them put onto a stack, or taken off the stack? Did you know you can swap elements on the stack?  Or write a program to prove that 2 + 2 = 5? Stack‑based programming dates back to the 1960s, and we at CodeRanch are starting new fora about programming paradigms. Come and find the different ways you can program your code.

[Tim Moores]

... and in order not to be too obscure about it: one example (probably the first one to become widely known) is the Forth programming language.

[Campbell Ritchie]

Yes, Forth a good example of a stack language. Chuck Moore developed it towards the end of the 1960s, and it is still is use nowadays.
