[Gretl-devel] off-by-one error in index loop?
Hi,
the following minimal demonstration script:
<script>
open denmark
loop i=1985:1..1985:4
printf "the period: %s\n", obslabel(i)
end loop
</script>
yields the following output for me:
<output>

loop: i = 1985:3

loop: i = 1985:4
the period: 1985:3
loop: i = 1986:1
the period: 1985:4

</output>
Notice that gretl's echo/message w.r.t. the loop index seems to be ahead
of the actual loop index by one. But the bug seems harmless, as nothing
substantial is affected.
Or am I missing something?
thanks,
sven
