5.6 Stack Manipulation

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.
