You can use anything. Just create a field and put any text into it. Then
put compress(fld x) into fld x
Save the stack and transfer it to the other platform. Then do:
put decompress(fld x) into fld x
It won't work for me. In re: your other note, there are no nulls and the
lines are not long; it is just plain ascii. So I don't think the problem
is with the source text, especially since I can reproduce the problem no
matter what I put in the field.
