my datas are organized in columns. In first column i have days of year, with 355 lines. In second column I have dates, with 355 lines of datas and from third i have 24 columns with temperature, with 355 lines.
1 01/01/2010 13,4 22,3 ... 353
2 02/01/2010 21 321 ... 245
. . . . .
. . . . .
. . . . .
355 21/12/2010 15 124 ... 193,3

I am getting just to read the first, the second and the tirdh column, but i need to create a array with all columns starting of third, obtain a array tem[24,355], but I am starting with IDL. I am sorry for my english, I am brasilian.
