Get VI to recognize a pattern of two 4 lettered uppercase words and insert
a comma in them

for eg


XHLP XCEL
APPL XCEL
STAK WILD
STAK WILD
STAK WILD

and make them

XHLP,XCEL
APPL,XCEL
STAK,WILD
STAK,WILD
STAK,WILD

In the above case it is easy, but I want a command which will do it for a
pattern like this anywhere in the file.

Thanx
Raminder

PS Is there a good book for VI. The man page is quite useless.
