Re: [Flashforth-devel] fl+ in FF4.8

[Mikael N. <mik...@pp...>]

Hi Mike,
Great to hear that FlashForth is working out for you.

The fl+ and fl- are correct in words.txt but reversed in the code.
Just correct the code and it will work the same way as in other FlashForths.
I will fix that in git.

The flash write should succeed like this:

fl+ 1234 flashVar ! iflush fl-

IFLUSH triggers the write to flash.

Waiting for the C-interface !
