Gforth maintains a number of separate stacks:

• A data stack (also known as the parameter stack) - for characters, cells, addresses, and double cells.
• A floating point stack - for holding floating point (FP) numbers.
• A return stack - for holding the return addresses of colon definitions and other (non-FP) data.
• A locals stack - for holding local variables.
