Have a list of field names in an array.
fld1, fld2, fld3, fldn..

These correspond to Field values in a text string.
I am trying to compare two files to see what field has
changed and return those values.
eg. fld1: changed from v1 to v2.

ex. file
Event ID<~>Container Number<~>Batch Number<~>Batch Type
0100<~>IDRFtest<~>RTR0100<~>RTR
0101<~>IDRFtest<~>RTR0101<~>RTR
0102<~>IDRFtest<~>RTR0102<~>RTR

Not being a perl expert yet, here is what I have so far... 
#!/usr/local/bin/perl -w

print "Please input ldap file: ";
  chomp ($FILE_LDAP = <STDIN>);
print "Please input sig file: ";
  chomp ($FILE_SIG = <STDIN>);

$FIELD_LIST_CMP1 = `grep "Event ID" $FILE_LDAP`;
$FIELD_LIST_CMP2 = `grep "Event ID" $FILE_SIG`;
if ($FIELD_LIST_CMP1 ne $FIELD_LIST_CMP2) {
   print "List of fields do not match\!\n";
   exit;
   }

$FIELD_LIST = `grep "Event ID" $FILE_LDAP`;
chomp $FIELD_LIST;
push @FIELD_LIST, split ("<~>",$FIELD_LIST);

@COMM = split /\n/,`comm -3 $FILE_LDAP $FILE_SIG`;

&Check_EV;
&Check_Text;
 
sub Check_EV {
# Check for <~> in the line.
  @FIELD_DIFF = grep /<~>/, @COMM;

# This gets list of Event ID's
  for (@FIELD_DIFF) {
# unix comm command seperates differences in columns
      if (!/^\s/) {
         @var = (split /<~>/, $_);
         push @EV_LIST, $var[0];
      }
  }
}

---------------------
sub Check_EV is where I need some help. Feel free to change anything..
I know there is a super hootie way of doing this. Please help.
