In my version gretl crashes, i.e. aborts
I'm not sure how that was happening but it should be fixed in CVS
(snapshots will follow tomorrow)
I need to assign some default value to a function argument of
strings type . Is there any way to do it? For string type it is
simply vname[null]. But for strings type I get "syntax error".
Maybe that should be allowed for arrays. But a null default is
already acceptable for a "pointer to" an array. For example:
<hansl>
function void arraytest (strings *S[null])
if isnull(S)
print "S is null"
else
print S
endif
end function
strings S = array(2)
S[1] = "foo"
S[2] = "bar"
arraytest()
arraytest(null)
arraytest(&S)
</hansl>

Do you really mean "crashes", or that an error message is generated?
I'm seeing the latter. That shouldn't be, and will be fixed, but in
the meantime you can use
matrices M = array(0)
to the same effect (get an empty array).
