Read lines till a blank line is encountered

Hi,

I have reached at a specified offset from the start of file. My requirement is that I want to read only those lines, which have the string READ / ALTER / UPDATE. As soon as, none of these literals are found in the subsequent line, I want to stop reading. Is there any feature of grep which can help me do this?

I saw one post in which someone has suggested using sed command. I could not follow it.

Please suggest.

tail -n $remPart filename.txt | head -n 100 | ............

The part in red is what I want. This should ideally be the terminating condition..
TIA
Saurabh
