when and if

[Geoff Nathan]

On the radio this morning I heard the following, which seems to be grist
for the mill:

 >When you hear [the song of the day], be caller number five and you will
win tickets to the Doo-Wop Dreams show.

For additional bonus points, what is the tense/mood/mode/whatever of the
verb form 'be' in the above sentence?
