Suppose the code is given as

</TABLE>

2
<PAGE>

abcdefghijklmnopq
uvw
[download]

It should be converted to

</TABLE>           abcdefghijklmnopq





uvw
[download]

I hope that the above example will explain u everything. If any pattern (like above it is found) then it will convert the pattern length and the no. of lines in the pattern found to spaces. But if suppose no pattern is found then it shouldn't convert the lines to spaces.
