"Where is the source, Luke?"

[mcctuxic]

Hi,

Do you know of a good source for forth definitions of the basic words - those zeptoforth as implemented in assembly language?

Do you know an Android USB terminal app, which works with zeptoforth? For "Zeptoforth on the go"... :)

Cheers!

Those were hand-coded in assembly and do not have Forth definitions. Also, they do things with registers that zeptoforth itself is not smart enough to do (as zeptoforth works primarily with R6 for the top of the stack and R7 for the address of the top of the data stack, and R0-R3 (and to a lesser extent R4 and R5) are used merely as scratchpad space, while the code written in assembly uses R0-R5 much more intensively than code written in Forth.

I have never used a terminal program on my Android phone or tablets, so I wouldn't know. Travis

Hi Travis,

sorry...I confused what wanted to say:
My question is completly unrelated to zeptoforth.
I am just curious how all these "words, which were given by the masters" :) would be implemented in Forth and
how many words are SO basic, that they can't be implemented in forth. A little bit like "how would be a computer like,
which has been bootstrapped from NAND gates alone"... kind of.

I the meanwhile I tried some terminal programs:
They fail either by not supporting ANSI, or being to old and could not handle
the newer access rights to usb devices for Android >= 11.
The one closest to work spit a row of alien control codes which each OK at me.

Cheers!

The number of words that must be primitives can be very small - look at eForth for instance. However this kills performance compared to implementing a greater number of words in assembly.

To get rid of these codes execute: false ack-nak-enabled ! false bel-enabled ! false color-enabled ! disable-line Note that these turn off ACK/NAK terminal synchronization, BEL on errors, color on errors, and the line editor (if you have it enabled). Travis
