Thanks, it works perfectly.
Can you explain: why you changed .* to . and the function of
{-}
'*' is greedy and matches as many characters as possible.
\{-} is non-greedy and matches as few characters as possible.
For example, take the following single-line of text:
The quick brown fox jumped over the fence. The quick brown fox jumped
over the fence.
If you use the following substitute command on the above text:
:s/The.*fox/The dog/g
The line will be changed to the following:
The dog jumped over the fence.
OTOH, if you use the following command:
:s/The.\{-}fox/The dog/g
The line will be changed to:
The dog jumped over the fence. The dog jumped over the fence.

"variable3 data" is correctly moved into the position formerly held
by "variable2 data". However, "variable2 data" is appended to the
end of the entire line and NOT moved to the position that was
formerly taken by "variable3 data"
Any ideas as to what's wrong?
