<div dir="auto">Hey Barry, <div dir="auto">An easy way of doing it would be to encapsulate all the file operations into an IF statement which uses either the isfilevar (<a href="http://www.ncl.ucar.edu/Document/Functions/Built-in/isfilevar.shtml">http://www.ncl.ucar.edu/Document/Functions/Built-in/isfilevar.shtml</a>) function or the isfilepresent (<a href="http://www.ncl.ucar.edu/Document/Functions/Built-in/isfilepresent.shtml">http://www.ncl.ucar.edu/Document/Functions/Built-in/isfilepresent.shtml</a>) function to check the existence of either variable in a file or the file itself. You just have to put an OR so that the operations are skipped, but the script is not interrupted, if either the variable or the file are not found. </div><div dir="auto">Cheers </div></div><div class="gmail_extra"><br><div class="gmail_quote">Il 17 dic 2016 5:29 PM, "Barry Lynn" <<a href="mailto:barry.h.lynn@gmail.com">barry.h.lynn@gmail.com</a>> ha scritto:<br type="attribution"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Hi:<div><br></div><div>I am downloading a lot of data and processing it, file by file.</div><div><br></div><div>It happens that sometimes a file is missing, or a even a variable within the file is missing.</div><div><br></div><div>How can I tell NCL to skip the read, instead of a returning an error and ending the program. </div><div><br></div><div>Basically, I want NCL to note errors, and bypass them, instead of terminating.</div><div><br></div><div>Barry<br clear="all"><div><br></div>-- <br><div class="m_4407414687066564818gmail_signature" data-smartmail="gmail_signature"><div dir="ltr">Barry H.
