Hi function writers,
there's a slight problem with the bcheck() function, see this example:
<hansl>
function void bcheckcheck (bundle b[null])
bundle targ = _()
eval bcheck(&targ, b) # error: 2nd arg is empty
end function
bcheckcheck()
</hansl>
The point is that the main purpose of bcheck is to handle a bundle with
options supplied by the user (here: "b"). So if the user is happy with
the defaults and doesn't supply such a bundle, I'd argue that bcheck
should simply accept that and do nothing.
I'm aware that the pass-through of a null value for the function
argument b is recent (gretl 2023b, AFAIK); so I guess that bcheck()
simply has to be adjusted to the new situation.
thanks
sven
