Executes and returns the job ID of the job filename.
This function is a functional version of :ref:`ex`, with the same set of arguments,
that executes a job. In addition to what :ref:`ex` does, it returns the job ID of the
new job that was started.

**Example**

::

    jId = FEX ("win1_XChange_xchange")

Will start Psion XChange in win1_xchange and return the job ID of the new job.

**NOTES**
In some combinations of SMSQ/E and FileInfo2 versions, there might be a clash of
extension names between FEX supplied as an SMSQ/E function (as described here)
and a function with the same name (but very different purpose) supplied by
FileInfo2. Later versions of FileInfo2 resolved this name clash by renaming the
corresponding function to EXF.
