Hi,
the first:
<hansl>
open data9-3.gdt
matrix check = {1;2}
series x = (price > 3) ? check[1] : check[2] # fails
</hansl>
A 1x1 matrix apparently is not allowed here. (If I do 'scalar s =
check[1]' first, then it runs.)
The second "issue":
eval pi # works
Not sure if 'pi' is supposed to be an alias for '$pi'. For me 'pi'
was a
typo and the fact that it didn't fail caused another bug that was a bit
difficult to track down.
thanks,
sven

True, it should. But let me add something quite off-topic. In my
experience, our "replace" function doen't get the popularity it deserves
IMO. Your example would become:
<hansl>
open data9-3.gdt
matrix check = {1;2}
series x = replace(price > 3, {1;0}, check)
</hansl>
which I find quite cool

That's a relic from the past. At some point we decided we'd deprecate the
dollar-less form, but never did in the end. Perhaps we now should.

That's absolutely right, I wasn't really aware of it. Looks like a very
versatile thing.

True, it should.
That's now fixed in git.

Indeed, quite nice.

It has actually been deprecated since version 1.9.10. From the
"backward-incompatible changes" log for 2012-11-05:
<quote>
The built-in constants "pi" and "macheps" have been renamed as
"$pi" and "$macheps". The old names continue to work at present
but they will be removed before long.
</quote>
So I guess their removal is now overdue. I'll fix that.
