Link to a file on disk?

I'm a bit lost in the manuals, looking for something that I believe exists but I don't know how to phrase it for effective contents/index searching.  Basically, my boss would like to be able to open a record about one of our cranes and click on a link (stored in the record) that will fire off a .jpg image of a scan of the crane capacity sheet.  We don't want to actually store the image in the record, but instead press a command button or something that will open the file stored on disk in the native image viewer which will display the image.  Can someone point me towards a command or page number that will set me along this path?  Thanks in advance.

@AsynchShell() page 150 of the Sesame 1.1 Programming Guide.

Syntax would be roughly

Code
Select All
Var vReturn as Int

vReturn = @AsynchShell(ElementName)
//ElementName is the name of the Element that contains the path to the file and the filename

Thanks, that's it.  Question: will FileExists() work to check the existence of a .jpg file before I hand the filename off to @AsynchShell?  The section of the book which details FileExists() (Text File I/O Commands) mentions that those commands only work with ASCII files, but the existence of a file seems pretty straightforward, and the command doesn't really work with its contents, so I wonder.

Can't hurt to experiment, I suppose..... Wink

That comment should not be so general. It applies to the File I/O commands that actually read and write files. FileExists() can check for the existence of any kind of file.
