Procedure
This routine just opens files and handles the movie part
(i.e. moving through the file in a loop or based upon your
keystrokes). The display program is called each time through the
loop, with all necessary variables and keywords (and _EXTRA=e)
passed in.
Example
To generate an image:
L4_lat_alt_day, 'geo', 1998079
L4_lat_alt_day, 'mag', 2002150, /LOG, /PS, /INTERP, FILENAME='foo.ps'
To watch a movie:
L4_lat_alt_day, 'geo', 1998079, 1999079, /LOG
To step through:
L4_lat_alt_day, 'geo', 1998079, /MANUAL, /INTERP
