Jonesforth-ARM

An ARM port of X86 JonesForth by Richard W.M. Jones rich@annexia.org at http://annexia.org/forth.

What have I changed ?

Very little. When reading tokens with KEY from a stream, the end of the stream causes the buffer to be cleared, the stream closed and then re-opened for /dev/tty. You can then continue using the interpreter interactvly with the added forth words.

The NEXT word is one instruction less (faster ?)

    .macro NEXT
    ldr r0, [r10], #4
    ldr r15,[r0]
    .endm

To Compile

gcc -nostdlib -static forth.s -oforth

To Run

forth < forth.f
