format lines on a file

Shell Programming and Scripting

Hi again:

I have a log file wihch has always this format:

DATA line 1
     DATA  line 2
^^^^^
     | Spaces or TABs

The first line always begins from the start, but the second begins with spaces or TABs,

Question:
How can I add the second line to the first one?
I mean this:

DATA line 1 DATA line 2

Thanks
Israel.
