gzcat into awk and then change FILENAME and process new FILENAME

I am trying to write a script that prompts users for date and time, then process the gzip file into awk. During the ksh part of the script another file is created and needs to be processed with a different set of pattern matches then I need to combine the two in the end. I'm stuck at the part where I have to change the FILENAME and FS part. Can anyone shed some light on this for me please.

Thanks

Code:

#!/bin/ksh
tput clear

dir=/my/dir/here/
ifile=/tmp/ifile
ofile=/tmp/ofile

echo "Enter the date and hour to run this script on [YYMMDDHH]: \c"
read file


/usr/bin/gzcat $file | /usr/xpg4/bin/awk '

BEGIN {
print "headers go here"
}


NR == 3 { print $2,$3"  --  "$4,$5 ; print "" ; next }

/^dise / {
        dipce = substr($2,4,1) * 1000 ; next
           }
/^LC/ {
        lec = substr($0,3,3) + dipce
        f++
        s = ""
        for ( i in arr ) { delete arr[i] }
        }
	   f {
		run some more stuff until gzcat is finished
              }

###Here I want to change FILENAME to "'"$ifile"'" ###

#Run some more awk code here while reading in "'"$ifile"'"




END {
Print some stuff from both processed file
}

cpp

CPP(1)							      General Commands Manual							    CPP(1)

NAME

       cpp - C language preprocessor

SYNOPSIS

       cpp [ option ...  ] [ ifile [ ofile ] ]

DESCRIPTION

       Cpp  interprets ANSI C preprocessor directives and does macro substitution.  The input ifile and output ofile default to standard input and
       standard output respectively.

       The options are:

       -Dname
       -Dname=def
       -Idir  Same as in 2c(1).

       -M     Generate no output except a list of include files in a form suitable for specifying dependencies to mk(1).  Use twice to list  files
	      in angle brackets.

       -N     Turn  off  default include directories.  All must be specified with -I.  Without this option, /$objtype/include and /sys/include are
	      used as the last two searched directories for include directives, where $objtype is read from the environment.

       -V     Print extra debugging information.

       -+     Understand C++ comments.

       The output file contains processed text sprinkled with lines that show the original input line numbering:

	      #line linenumber "ifile"

       The input language is as described in the ANSI C standard.  The C compilers do not use cpp; they contain their own simple but adequate pre-
       processor, so cpp is usually superfluous.

FILES

       /sys/include
	      directory for machine-independent include files

       /$objtype/include
	      directory for machine-dependent include files

SOURCE

       /sys/src/cmd/cpp
