Hi Yu, 

Perhaps as if not more succint is to open the text file in a text
editor, and replace every instance of "  " (that was two spaces) with
" " (one space).

You may have to do it until a message comes up that
- -no instances of "  " (2 spaces) could be found--

This assumes that you do not have a string variable (for example an ID
variable) that has two spaces within it which are meaningful, such as
"ABCD  EFG HIJK". 

Thats the only caveat I can think of. 

Best, 

Dan
