Re: problem with yyyyddd_to_yyyymmdd

Got it! Thank you very much!

Can I ask one more question?
Is there a way to find out problems like this "add a float[ dd(j,1) ] and a
string and then convert the result to an integer" one?
Since the output looks like what I want and there is no error message about
this.
I guess I used the bash script idea here.

Thank you very much! I really appreciate it!

Best,
Wenshan
