[REBOL] Re: getting rid of empty string in a block.

From: cybarite:sympatico:ca at: 13-Mar-2002 12:01

one way to remove empty strings from a collection is
   difference ["A" ""  "C" "" "E"  ] [""]
but because it is difference, there must be an empty string in the first
collection.

To get around that you can add one then remove all with append or union:
   difference union [""] ["A"  "C" "E" "" "F"   ] [""]
or
  difference union [""] read/lines %some-file.txt  [""]
