[Amforth] Named Parameters and Local Variables

I like programming in Forth but I spend an inordinate amount of time doing stack manipulation to get all of the variables and parameters in the right spots in order to operate on them. Most of the time I spend more time on the mechanics of programming in Forth then on the logic I am trying to code.

[Amforth] Version 5.3?

[Amforth] Multi Line Comments

Enoch If that is the case then it is impossible to comment out code if you have embedded stack diagrams in it. That results in nested comments which are illegal. I guess I'm back to trying to add multi line comments with my own code. Craig Lindley If you’re one in a million, there are now seven

[Amforth] Multi Line Comments

Enoch, I just tried out multi line comments for the first time using the shell and it doesn't seem to work as I would expect. Here is a little bit of the code I am working on \ Define some named bit fields &5 &0 &4 bitfield: READ_BL_LEN &6 &0 &2 bitfield: C_SIZE_HIGH &7 &0 &8 bitfield: C_SIZE

Thanks Enoch, I hadn't realized the shell supported multi line comments and since I only use the excellent shell, I can accomplish what I want without extra code. Great, -- Craig Lindley If you’re one in a million, there are now seven thousand people exactly like you. -

[Amforth] Multi Line Comments

I know I will probably get flamed for wanting multiline comments but I think they are really handy when writing / debugging code. I thought it would be a trivial exercise to add multiline comments but I was wrong. I tried this code \ Refill if at end of input line : ?refill( --- f )

Re: [Amforth] Problems with Turnkey

I figured out what my problem was. It was the fact that when running as a turnkey application I didn't give my application any delay to allow the hardware to stabilize. I added 500 ms before the startup code and the problem when away. On Thu, Dec 5, 2013 at 10:15 AM, craig and heather

Re: [Amforth] Build Issues

Looking closer at the build results I assume the eseg would be destined for the eeprom. Could it be that the hex file has both parts in it? And if so, what are the chances of success by just programming the single file onto the Arduino? I would try this but I'm fresh out of Arduino Uno's just now.
