Problem with dynamic variables outside the loop

Hi All,

Shell is ksh

I've given portion of the script here to explain the problem.

It will accept 2 input parameters .

Code:
in_file1=$1 
in_file2=$2 
outbound_dir=/home/outbound 

for i in 1 2 
do 
  eval file$i=$outbound_dir/\$in_file$i 
  eval echo "filename is \$file$i" 
  eval temp_file=$outbound_dir/\$in_file$i 
  eval FILE$i_LINE_COUNT=`wc -l < $temp_file` 
  eval echo "Total lines in file$i are \$FILE$i_LINE_COUNT" 
done 

echo "file1 name outside loop is $file1" 
echo "file1 count outside loop is $FILE1_LINE_COUNT"

When i am displaying file1 and $FILE1_LINE_COUNT variables inside the loop its giving correct values.

But ouside the loop getting correct value for only file1 variable not getting for $FILE1_LINE_COUNT variable.

can you pls help me.

NAME
diff3 - 3-way differential file comparison SYNOPSIS
diff3 [ -ex3 ] file1 file2 file3 DESCRIPTION
Diff3 compares three versions of a file, and publishes disagreeing ranges of text flagged with these codes: ==== all three files differ ====1 file1 is different ====2 file2 is different ====3 file3 is different The type of change suffered in converting a given range of a given file to some other is indicated in one of these ways: f : n1 a Text is to be appended after line number n1 in file f, where f = 1, 2, or 3. f : n1 , n2 c Text is to be changed in the range line n1 to line n2. If n1 = n2, the range may be abbreviated to n1. The original contents of the range follows immediately after a c indication. When the contents of two files are identical, the contents of the lower-numbered file is suppressed. Under the -e option, diff3 publishes a script for the editor ed that will incorporate into file1 all changes between file2 and file3, i.e. the changes that normally would be flagged ==== and ====3. Option -x (-3) produces a script to incorporate only changes flagged ==== (====3). The following command will apply the resulting script to `file1'. (cat script; echo '1,$p') | ed - file1 FILES
/tmp/d3????? /usr/lib/diff3 SEE ALSO
diff(1) BUGS
Text lines that consist of a single `.' will defeat -e. Files longer than 64K bytes won't work. DIFF3(1)
