    Mike:

    Since txd & rxd are constants, why not do the following: e.g., #6 TO txd #7 TO rxd BACKUP, then reboot.

    TO is defined as : TO ' 2+ ! ;

    Re: The Forth Dimension.

    I note that the forth fft that Heater referenced in post #110 actually computes the fht of data, which is then transformed into the fft. This has already been accomplished in PropForth.

    Poll: Re: Which Forth to use?

    Both PropForth and Tachyon, depending on the application. PropForth for larger applications.
    Tachyon for access to spi devices. A 2-prop system, one running PropForth and the other Tachyon.
