When starting in Forth, one typically learns about the stack and its operators (DROP, DUP, SWAP, etc.) first, so it's natural to think of these as being among the primitive operators. But they're not. Each of them can be broken down into operators that directly manipulate memory and the stack pointers.
26 wrz 2016 · Forth uses a dictionary to look up defined words. Forth has two stacks, a parameter stack and return stack. The parameter stack is used to hold values being operated on, whereas the return stack is used to hold return positions from jumps to nested words.
7 kwi 2022 · Forth is a procedural, stack-oriented, reflective, and concatenative programming language developed by around 1970. If any or all of those paradigms sound strange to you, don’t worry, we’ll explain each one when appropriate. In this part, we’ll limit ourselves to procedural and stack-oriented for the time being.

Two-Stack Abstract Machine. At the most superficial level, Forth is a directly executable language for a stack-based abstract machine. In its essential form, the Forth abstract machine has a program counter, memory, ALU, data evaluation pushdown stack, and subroutine return address pushdown stack.
13 lis 2020 · Forth brings along all operators common in mathematics. It uses the reverse Polish notation (RPN) when processing calculations. This means that the operands are entered first and then the operator to be applied to them.
Forth was created by Charles H. Moore in the 70s. It is an imperative, stack-based language and programming environment, being used in projects such as Open Firmware. It’s also used by NASA.
