I don't think this is possible because .Net use it own calling

I am trying to use the table control in JQT.
It works fine when my data doesn't contain " characters.
My fields contain spaces, so I applied dquote to them as the docs
suggested. This encloses the field in "" and doubles any " characters
in the fields.
It seems that QT doesn't recognize ""
dissect runs the sentence twice, once as you give it and again in the
highly instrumented form needed for dissection (I do this just to make
sure they produce the same results). When the sentence has a side

Yes. The second entry in FiF is labelled "In folder:", and folders are
documented in wiki page
http://www.jsoftware.com/jwiki/Guides/Folders%20and%20Projects.
Package manager will often have descriptions of every addon it knows about.
There could be a wikipage that lists them all along with any links to usage
help pages, and perhaps links to addons/packages that are not part of the
distribution.

Apparently my question and its purpose was misunderstood. I was not asking what

There may in fact be something to that Raul,

We don't plan to resurrect winapi, as the windows API is well enough

For grid, the table control should handle most uses, e.g. see the Package

Dear All,
I've come across a puzzle
and would be glad if someone could explain it.
In a few words, I have a variation of collatzv which is a one-liner
(c1 below) and the very same verb spread over several lines (c2 below).
The second is nearly twice as fast as the first. How come?
