given that at least two new loop bugs have been reported in very

produce other related bugs in the near future.
So maybe the loop stuff should be systematically tested before a
new release is made.
Thanks, Sven. I've tested the new code on a fairly wide variety
of scripts. The bug that you discovered was a localized parsing
issue, now fixed. The "bug" that Yuniarto found was, as I said
subsequently, a bug fix. Under the old scheme the loop index
variable was sui generis, but now it's a proper scalar variable,
which staves off various potential problems. A side effect of
that is that you can't use as loop index an identifier that is
already claimed as the name of a series (or matrix). But this is
already strongly implicit in gretl's variable-type system.
I certainly don't want to discourage further testing; but I'm
fairly confident that the current loop code is "right".
Allin.
