[Gretl-devel] argname error

Hi, not sure why the following fails, given the documentation of 'argname': <hansl> function void ch(matrix m[null], string s[null]) if exists(m) eval argname(m) elif exists(s) eval argname(s) endif end function string s_in = "hey" ch(, s_in) # error, expect "s_in" ch(, "hey") # expect "" (anonymous), got error (once we get here) </hansl> This is with April 25's snapshot on Windows. thanks sven
