At last i have 2 files one having the records in a.txt file & another file having match counter & not match counter values.

But this is not working, please help

Code:
zcat filename.tar.gz | awk -v mon="07" '
BEGIN {
 if (( (substr($0,26,2)=="02") && substr($0,84,2) == month  ))
  print $0 >> "a.txt"
  ++matchcounter
 else 
 ++notmatch 
 ;}
END { print matchcounter","notmatch >> "countfile"}
'

Try without BEGIN
Code:
zcat filename.tar.gz | awk -v mon="07" '
    {
 if (( (substr($0,26,2)=="02") && substr($0,84,2) == month  ))
  print $0 >> "a.txt"
  ++matchcounter
 else 
 ++notmatch}
    END { print matchcounter","notmatch >> "countfile"}'

EXIGREP(8)                                                    System Manager's Manual                                                   EXIGREP(8)

NAME

       EXIGREP - Search Exim's main log

SYNOPSIS

       exigrep [-l] pattern [log file] ...

DESCRIPTION

       The  exigrep  utility  is  a  Perl script that searches one or more main log files for entries that match a given pattern.  When it finds a
       match, it extracts all the log entries for the relevant message, not just those that match the pattern.  Thus, exigrep can extract complete
       log entries for a given message, or all mail for a given user, or for a given host, for example.

       The -l flag means 'literal', that is, treat all characters in the pattern as standing for themselves.  Otherwise the pattern must be a Perl
       regular expression.  The pattern match is case-insensitive.  If no file names are given on the command line, the standard input is read.

       If the location of a zcat command is known from the definition of ZCAT_COMMAND in Local/Makefile, exigrep  automatically  passes  any  file
       whose name ends in COMPRESS_SUFFIX through zcat as it searches it.

       This manual page needs a major re-work. If somebody knows better groff than us and has more experience in writing manual pages, any patches
