Re: [Gretl-devel] Backward compatibility
In CVS and Windows snapshot you can do the following (revised
version of Ignacio's sample script):
<script>
function sillyfun (string foo, series x)
series @foo_f1 = x+x(-1)+x(-2)+x(-3)
series @foo_f2 = x+x(+1)
list outlist = @foo_f1 @foo_f2
return list outlist
end function
open data9-9
string sname="nocars"
list alist = sillyfun(sname, nocars)
print alist
</script>
Alternatively, you could give the string argument to sillyfun as a
quoted string literal:
list alist = sillyfun("nocars", nocars)
I just downloaded gretl from CVS and the script does not work (In Kubuntu
Linux). The output I obtain is
gretl version 1.6.6.pre2
