hello, good day.

my test text for forth gives an error message.
I transferred the text to a dsk.d64.

when I load the file with "include test.fs"
the error message appears.

your other fs work.
they are on the same disk.

where is the error.

thanks.
regards

How are you copying the file? You probably have the wrong line endings. If you're using c1541 I think you have to specify ,s to ensure that the file type is correct.

thanks for the info.
the end of the line was missing in the text.

your vforth has been wonderfully expanded.

greetings

how do you do this character " ' " in vforth : 'test
with winvice in vforth?

thanks.
regards

That will depend a lot on which version of vice you're using and what keymap you have selected. With new versions there are positional and symbolic, along with translation for localized host keyboards. Best ask in "Emulation and Cross Development" for help.

hello, good day.

I started the vforth rom and entered my program:
: hello ." hello vc20" ;

now I want to save the whole vforth with my program as myforth.prg.

how do I do that please?

thanks.

hello, good day.

how can I use the address from $a000 - $bfff with the vforth rom?

thanks.

I'm not sure I understand your question, you load the image into $A000 and start it using

Code: Select all

xvic -memory all -cartA vforth.rom

There's no simple way to make a completely standalone executable. You can create a dictionary that automatically executes a word on loading using the AUTOSAVE vocabulary, example shown here

hello, good day.

where can I find 2000 bytes free for myself with an address to use?

where can I find the memory list for the vforth.rom?

where can I find the memory list for the vforth.prg?

thanks.
greetings.

where can I find 2000 bytes free for myself with an address to use?

The FORTH approach to memory allocation is to take it from the free space at the end of the dictionary using

Code: Select all

2000 allot

This leaves the address of the space on the stack.

where can I find the memory list for the vforth.rom?

where can I find the memory list for the vforth.prg?

The memory map which shows these is in docs/memory-map.txt

Could something like this (full-screen text editor, mostly ANS-FORTH) ever make it into VFORTH or would that be rather illusory, considering the limited heap?:
