Overview of Forth

Forth is a low-level language.

• Forth provides bit-level operations and selection of number base.

  • The user can work directly in hex and binary bases --- the language of hardware. Results of single hardware operations, such as writing to a port, can be verified immediately.
    
    

• Most Forth systems provide an assembler

  • The assembler is often a Forth program itself. The programmer can switch back and forth between Forth and assembly code within the same program.
