Re: [Flashforth-devel] n=

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

Hi,
Check n= in the linked document.

https://flashforth.com/wordsAll.txt

Strings can only be defined in flash with ." and S" within an word 
definition.
With ," you can append a string to the current memory space outside a 
word definition

You can copy a string from flash to a ram buffer with PLACE.

: s1 s" hello" ;
ram create str-buf 20 allot
s1 str-buf place

str-buf 1+ s1 n=

Something like that should work.

Or something like this

ram here ," hello"
1+ s1 n=

Note that repeated use of ," will use up memory.

With ,"
