Could anyone help me out. I have about 70 different files with a line
containing date(Month and year) in each file. I want to pick the date
from each of the file and plot it against 5 columns in each of the 70
files. I tried to use julday(month(i), day(i), year(i)) but anytime i
tried to call it, it comes out with the following error message "There
is no year zero in the civil calendar"
I shall be most grateful to get an immediate assistance
Thanks
Isreal

when you call
IDL> julday(month(i), day(i), year(i))
your value for year(i) is zero.
so your error is happening before the julday call.
(perhaps your year array wasn't fully populated, and you
have default zero values or something like that)
cheers,
