If I understand you, you'd like to insert the value from certain
variables ?

This of course depends on your shell however I've never encountered
one that dereferences variables by quoting them and surrounding them
with plus signs.  You may have gotten confused by awk scripts where
these kind of constructs can be seen.  However, in that case they look
like "CDEF:cout=" + currentOut + ",UN,0," + currentOut + ",IF"
and then the quotes are *not* around your variables.

My guess is that you should use CDEF:cout=$currentOut,UN,0,$currentOut,IF
