It should be, yes. It will just be FALSE, since lSeq is empty.

"" and empty are the same -- the latter is just a constant name which 
represents the former.

This looks ok to me, and should generate a list of unique, non-empty 
lines from gInitialList.
You may want to clean up the trailing return when you are done:

delete last char of lSeq
