I don't know what you mean by your "labels coming up undefined", but I
did some issues. The time structure is not defined in your code
snippet. Ok, so I defined it as
IDL> time = {year:2010,month:6,day:23,hour:12}.
Your case statement is not complete. Add an endcase to end the (idx
eq -1): begin.
If the 'time' I manually entered matched the 'time' structure, there
is no case statement to handle it. Add an ELSE: in your case
statement to handle that.
Then it'll at least compile. I'm not sure what you're doing with it.
Regards,
Brian
