Block processing using awk

Hi,

I want to know how to process block of lines using awk.

For example,

Sample File:

Code:
 
20130113 18:07:50 PROCESS START
ABC
XYZ
DEF
20130113 18:07:52 PROCESS END for ID 123

20130113 18:07:52 PROCESS START
ABC
XYZ
DEF
20130113 18:07:53 PROCESS END for ID 124

Code:
 
Desired Output:
ID|Start_Time|End_Time|Duration(End_Time-Start_Time)
123|18:07:50|18:07:52|2
124|18:07:52|18:07:53 |1

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
