Re: [Gretl-users] why the error
Allin,
Please forgive the silly question, but just out of curiosity
Why is the double minus "--" ok?

You're mixing up the 'dummify' command with the 'dummify()'
function.
Only the command takes these double-dash-style options like
"--drop-first". For the function you have a second argument, please see
the help for that (haven't used it myself yet).
Remark for Allin and Jack:
BTW, I think the error message is strange insofar as IMO the parser
should complain already about the "--" in there, not about the
"drop"
word, no? But perhaps this has been changed since last release.
The "--" is in principle OK if interpreted as "minus minus",
as in "y = f(x) --a".
Allin
