determine if a container is a reference or a stored file?

[Neuronal Nerd]

Is there a way for a calculation to determine if a particular field contains a reference to file or the actual file it self?

I'm putting together a script that will do one action if it is a reference (i.e., open the file) or another if it was a stored image in the container (i.e., export that image for opening)?

Thats pretty easy:

Sign(PatternCount ( GetAsText ( aContainer ) ; "/" ))

Which returns 1 if it's a referenced and 0 if it ain't!

It might be a back slash to search for for "PatternCount" instead on a windows machine.

Which then perhaps better can be obtained this way:

Sign(Length(Filter("/";GetAsText ( aContainer ))))

...if the solution is x-platform'ish deployed!

thank you!

I believe all paths are OS independent, that is they are FM paths and contain only forward slashes.

Even the Sign( in my second suggestion is ridiculous - since I reversed the order input and filtering ... so one slash being filtered, is always one or zero. I wondered why didn't find it instead Barbara??
