Personally I would do this in two stages,
Firstly if you replace each 0B with a 10B using
btest[where(btest eq 0B)]=10B
you can now print btest then you get the line breaks (This can be used in
message boxes etc.)
Or if you want to go one further then split them using
stest = strsplit(string(btest),string(10B),/extract)
print, stest
This is a jest
help,stest
<Expression> STRING = Array[4]
I hope this is of some help.
