No, the McIDAS area files do not need to be modified to view them in GEMPAK.
You can use NSAT with the File->user_defined browser to open the file and view
the area files, or any of the text interface programs by setting the areafile 
name
in SATFIL and defining PROJ=sat.

In order for Garp, or the FILE->standard gui popup widgets to display the
file names and types, the area files need to be named something more
explanatory than "AREA0120". to do this, the $SAT environmental variable
points to the top of a directory tree with the area files renamed as 
described in:
