Modifying your own version of FF

I occasionally modify my copy of FlashForth source code.

Of course, Mikael has requested in the source file header:

; Modified versions of FlashForth must be clearly marked as such, 
; in the header of this file, and in the identification
; displayed by the word VER.

It is also nice to know exactly which version/subversion of FF is installed in the processor being worked on.
Here are some examples for my copy of FF5.0 PIC18:
