Hmm. Do I get this right? In this case
* we need to create a new fcode lookup table every time we run a
* This has to happen from within the packages dictionary context,
i.e. if we have several bus drivers, the r[lw][@!] words have to
point to the correct words.
* We can not use defer words for this as we might have different
Maybe we can have those words be wrappers doing ' real-rl@ execute
or something similar? on the other hand it might not be wise to work
Currently I do
' end0 , ... to create the lookup table
this would have to be replaced by something like
" end0" $find if , else ' ferror , then
to catch the words current version dependant on the dictionary.
hm. this will probably not make things faster...
