I had already mentioned this bug, but I can't find where. Anyway, it
is still here. With a function declaration like this:
function foo ( series a, scalar b[0::1], scalar c[0:2:1], const list
d[null], scalar e[0:2:0])
I'm supposed to be able to invoke the function just with a simple:
foo(a)
where a is a a series obviously.
Instead, gretl wants at least:
foo(a,b,c,d)
because does not accept the absence of the list, whereas it should be
allowed by the [null] tag.
Cheers.

Could you post a complete test case, please? I think there must
be some special complication at work, because the following script
works fine here:
<script>
function myfoo (series a, scalar b[0::1], scalar c[0:2:1],
const list d[null], scalar e[0:2:0])
print a -o
print d
print b c e
end function
open data4-1
myfoo(sqft)
</script>
It prints:
<output>
? myfoo(sqft)
Obs a
1 1065
2 1254
3 1300
4 1577
5 1600
6 1750
7 1800
8 1870
9 1935
10 1948
11 2254
12 2600
13 2800
14 3000
b = 1.00000
c = 1.00000
e = 0.00000
</output>

Well, you are right that wasn't the problem. The problem was that the
null list was passed to the ols command and it caused the error.
Now the point is that the error message may mislead, and perhaps it
should be changed.
In fact, this way the ols produces the error msg:
"Command has insufficient arguments"
If that happens to a function (the case I thought) we have:
"*function_name*: not enough arguments
Command has insufficient arguments"
The best would be having a similar msg for the ols as well:
"*command_name*: not enough arguments
Command has insufficient arguments"
But that is far from being an urgent matter.
Cheers.

Ah, there's a difference that should be resolved, between the
gretlcli output and the GUI script output.
<script>
function myfoo (series a, const list x[null])
ols a x
end function
open data4-1
myfoo(price)
</script>
Running the above with gretlcli produces:
<output>
Command has insufficient arguments
error on line 1 of function myfoo
ols a x
gretlcli: error executing script: halting
myfoo(price)
</output>
which seems to me fine. But it's true, in the GUI the error
message is not so informative.
