Didn't find it in the dictionary, but I do see that now in the

constant quote is "\q" ?
Yes.
The language guide explicitly states "Note: Constants are not
currently implemented, although the syntax is recognised." What am I
supposed to make of that?
That's a bug in the language reference - it should say that only literal
values are supported at present, general (constant) expressions are not.
That's unfortunate. In LCS I often change the itemdelimiter in order a
to parse complex strings. The lack of the ability to manipulate things
at this level is a serious detriment to text parsing, which is one of
the main strengths of LCS.
Indeed - it is a *great* strength of LCS and is very important in the
domain of things which are written in LCS. The development of LCB has
mainly focused on things which LCS cannot do - like calling foreign
functions and being able to render complex visual representations of
data with a much lower overhead than is necessary in LCS.
Ah. So the dictionary isn't a good place to look for things. I'll
spend some time working my way through the language reference instead.
Heh - as Ali said, the docs and such need a fair bit of work :)
Similarly, word and token are 'tokenized chunks' - they action could
be
described by a regular expression.
See above (itemdelimiter).
See above (strengths of LCS vs LCB) :)
Now, I'm not saying that LCB shouldn't have better ways to manipulate
text - closing the gap between LCS and LCB is an important goal;
however, it seems wiser to get the things working in LCB which LCS
cannot do first, before replicating functionality LCS already does
really well.
Warmest Regards,
Mark.
