Hi.
To handle IMMEDIATE words there is a variable called G4IMMEDIATE -
turn it on to make the next colon definition immediate.
Since G4 is a simple one pass scriptor, there is no other way to
accomplish it. The header and following stuff has allready been
written when you reach the classic

Hi Jan.
I would add the word to amforth-x.x/appl/myproject/words/uitvoer.asm
and append them in dict_appl.inc in the way words are included there:
..
.include "words/uitvoer.asm" ; my first assembled forth word

Recently someone asked how otherwise imported subroutines (c-code)

You may use icall of AVR instruction set to do so.

Interpreting a commandline speeds up if yo

Hi Al.
..
The problem is once you mess up the flash you have to reprogram.
Adding a simple 'restoresystem on reset' helps allot. It just takes a
copy of the original system vectors and puts them back into eeprom.
As long as you did not overwrite amforth below DP by mistake this
will work.

maybe this version works. It copies the _entire_ system vector to
