Let me think about this a bit - and others please step in.
I remember translating J for C and I basically remember just the . being a
real problem sometimes in flowing text at the end of a speach sentence and
the J sentence at the end of it without some separation.
.;():"[]and{} are all part of both ordinary speach as well as J and pretty
much anything else so it is kind of hard to find a good easy way to
separate between the two.
takes the sum of items of y.
Here we see it perfectly again.
is it y or is it y.
( Now I was going to place ? after y. on last line like y.? and that just
clarifies how difficult this is as ? is also part of J)
This is pretty hard.
Maybe not have J sentences not at the end and then not . there after the J
sentence?
One thing I noticed in dissect is if I do
dissect 'verb noun'
it does not open the verb to display.
I used
verb noun f.
and the result from that and if it was tacit it was fine but if the result
contained x or y the dissect did not like it even if it accepted the verb
noun before the f. operation.
