Vino,
Your substitution will replace all instances of '.', including '19.23'.
The Regular Expression ' *' means zero or more instances of space.
In other words, it will consider anything as true, as any non-space
character means zero instances of space.
Also the solution should keep the space after the name.
Here is one possible solution:

Code:

:%s/ \./ NULL/

It should have read

Code:

:%s/ \{1,\}\. \{0,\}/ NULL/g

Ah.. its an overkill !
