I've used curl with FileMaker several times, it's a great way to extend
Fm's functionality.

It's possible to read the error number that curl returns and make
decisions based on that, but
what I prefer to do is create a set of batch files to execute the
common curl tasks, and use the
then call those batch files from within FileMaker. The advantage of
this is that you can use the batch
file to check for the existence of a file before even calling curl. You
also have the ability to generate
your own return codes, and make them sensible for your specific
purpose.

Windows batch files also support looping, branching, and testing
various attributes of files.
So the batch file can check to see if the file exists, and if it
doesnt, the batch file can return an error
code you control. I believe that will be a lot easier than trying to
parse output text.
