Isn't there a routine for looking up the adresses in Flash?

BTW: I'm having the same problems with the file routines I've worked on
(and hope to continue on sometime). You really can't be shure where a file
is in memory, unless you control everything (_insertmem, _deletemem, etc).

Small routines can be placed on the stack, variables also, but probably you
would want to use some of the 'gaps' in memory (or use writeback). Some
places in RAM are almost(...) never used.
