Searching a text list in a global field

[smilemaker]

I'm impressed at what can be done with filemaker as I read the forum. I'm new at using the program. I'm hoping that the following can be done.

I'm using Troi to list the graphic files in specific folders as the user specifies. These folders hold patient jpegs of photos and x-rays. I would like to be able to search with a script the list of file names in a folder to determine which file is the most current. Each item(filename)is named by date and time created. If this can be done,I could use Trio to display the most current x-ray file for the doctor.

Can a global field that has a text list be searched? Is it possible to look at each list item one at a time in some type of loop script?

Is there a better way to do this. I'd be very grateful for any suggestions.
