It stores the blocks in flash, so it eats away from your free program memory unless you have a 128 KB or bigger flash in your PIC24 chip."
With the release of the Scamp3e users get an extra 2M Dataflash: https://udamonic.com/what-is-a-scamp.html
Thus the possibility appears to create a screen oriented file system (1024 bytes: 16 lines 64 characters each).
Do you intend to publish your 'block words' and the 'full screen block editor'?
That would be great!
im interested in use it if we can use the 2MB extra flash memory. in other case my idea is to create a text files save-load tool , to keep the programs saved in this extra memory.
I have some initial code written, that works somehow. Don't exactly remember. I think there was problems with loading blocks in case an error is encountered. The interpreter aborts on a missing marker word and the loading is prevented, making marker unusable with blocks.
Just tried to use it. It uses some special words, that I have since deleted from FF. Need to check what it was supposed to do.
I'll give it a try :-)

I published it. block.fs for PIC18 and Atmega, block24.fs for PIC24 and edit.fs.
You can play with it, but it is experimental, so don't expect too much.
The editor requires a VT100 capable terminal.
Only tested with minicom on Linux.
Thank yoy Mikael.
I tried block24.fs/edit.fs on my Scamp3.
Unfortunately some words/definitions are not available on Scamp3 ☹
Are you sure? All words are present on my scamp3e.
You have to load the files core.fs case.fs vt100.fs yourself first.
Then you can load block24.fs and edit.fs.
There is a hint about it edit.fs and block24.fs.
sendm is the command in ff-shell.py for sending multiple files to the serial line.
What terminal program are you using to send files to the FF serial line ?

Up till now I used CoolTerm on macOS.
In the future iTem2 on MacOS
Will give it a try as soon as the Scamp3e board arrives.
I'll let you know the result of course.

The scamp3e is not needed specifically. The block/edit code works the same on any scamp board.
OK. I'll try again on my Scamp3. (has to wait until this evening...)
Hey Mikael!
I succeeded to build block24 and edit on my Scamp3.
VT100 terminal emulation on macOS with iTerm2 app [https://iterm2.com] seems to work :-)
Now I have to get used to the editor/screen key-commands.
Future steps:
I have attached a 32 kByte eeprom (I2C interface) AT24C256. So room for 32 screens.
The AT24C256 is read/write accessible via Pages of 64 bytes each.
