[ncl-talk] Skipping Missing Files

[Guido Cioni]

Hey Barry,
An easy way of doing it would be to encapsulate all the file operations
into an IF statement which uses either the isfilevar (
http://www.ncl.ucar.edu/Document/Functions/Built-in/isfilevar.shtml)
function or the isfilepresent (
http://www.ncl.ucar.edu/Document/Functions/Built-in/isfilepresent.shtml)
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.
Cheers
