1) Please do not use "URGENT" in the subject. It is not urgent to us.

2) Please be much more specific. I have no idea what your problem is.
Provide an example of what you're trying to do and what the result is
expected to be.

Say cell value=  my world

I wanna append few lines  to this text.

say I wanna make the cell value =
one
my world
two

This example does not fit "few lines". It looks like you simply want to put
a liner feed before and after your cell's information. There are two easy
ways:

- If you are appending with quoted strings, put Alt-Enter inside the strings
at the places you want the line feeds.

- Otherwise, concatenate CHAR(10) into your result at the places you want
the line feeds.

You will need to turn wrapping on for the cell.

Sorry i don't get it.
I have long html  code liines to be prefixed & suffixed to a cell
value.
The html code  also has double quote charcater.
