File permissions within a snap

[Jenny Murphy]

Hi,
 Do I need to define the location of SNAP_USER_DATA. Currently I added the
following line to a wrapper script that already runs in my app :

echo "User Data = " $SNAP_USER_DATA


The result is
 User Data =


Thanks a lot for you help. I guess this stuff is very basic but I am having
to get up to speed quickly on snappy.
