[Gretl-users] Passing a list of series to a function

Hello, I am using Gretl 1.9.12cvs on WIN 8. Is there a way to pass a list series to a function? I used the following function declaration: function void dplot(list lstDIV, string filetype, string strTitle[null], string strDisc[null]) string ddat = varname(lstDIV[1]) sprintf send "%s", date(firstobs(@ddat)) end function but get this error The symbol 'DQ_us' is undefined *** error in function dplot, line 24 So I am able to pass the list but the individual series are not accessible? Anyway around this? Thanks, Logan
