Hi Ross,

Yes, I did try that... but what I want is string parameter that changes based on whether or not you've checked a checkbox (or a way to change the label of the output based on whether or not the checkbox was checked).  So my idea below did work, but it seems like a hack.  Which is why I was wondering if there was a better way.

Nikhil, did you try as Shaun and others have suggested? Any available
string parameter can be used in a label as far as I can tell.

This is a common idiom - ask for a string ('title') to describe the
job/output for posterity, then in an output:

<data format="foo" name="output1" metadata_source="input1"
label="${title}.myext"/>

There's even a built in ${on_string} if you just want the file name
plus some history ids?
