This is entirely trivial, but anyway: I realised that the manual somehow
underplays the possible operations on arrays ("At present only one
operation is available for arrays as a whole, namely appending", p. 78),
as subsets of an array can be extracted using matrix syntax, as in
<hansl>
strings S = array(3)
S[1] = "a"
S[2] = "b"
S[3] = "c"
strings Q = S[1:2]
</hansl>
which starting from the array "a","b","c" produces the array "a","b".
This actually came handy to me (I started with a panel of units and
their labels in an array, then dropped some units and needed to redefine
the array), so it may be worth it mentioning it in the manual.
You're totally right, Stefano.
I think we really need to find a way on how to make it as easy as
possible for people to contribute to the project. That affects not only
hansl packages but also contributions on the manual, the help text apart
from translations. But people also contribute by writing articles, blog
entries etc. on how to work with gretl.
