Something like this might work

awk -F: ' /^Latitude:/ { LAT=$2 }
          /^Longitude:/ { LONG=$2 }
          END { print "svAdena " , LAT , LONG , "waypoint 0 0 0 0" } '
>> way.txt


This awk script assumes a lot about the format of the message. It
doesn't check that the lat and long data are numbers or in a good format
etc. I split the awk line onto multiple lines for readability.  You
could pipe the message body directly with procmail, or use something
like the following in a bash script.

awk '...' < message.txt >> message.txt


awk is great.
