I am an Awk newbie and cannot wrap my brain around my problem:

Given multi-line records of varying lengths separated by a blank line I need to skip the first two lines
of every record and extract every-other line in each record unless the first line of the record has the word "(CONT)" in the line
then skip the second line and append those every-other lines to the previous records every-other lines.

I hope that makes some sort of sense. I tried the following awk to get every
other line but it doesn't come out right. So i haven't even begun to try to figure out the rest of my problem....
awk '(((NR % 2) == 0) && ( NR > 2 )) {print}' ~/Desktop/datafile

Any programming help would be appreciated! I have provided the following example input data of four records:
