Is $filename name /tmp/odbc.ini.2014_old or /tmp/odbc.ini_old?

The code shown above will remove the line matching the string. For replacing string try updating to:
Code:
#!/usr/bin/perl

use strict;
use warnings;

my $filename = '/tmp/odbc.ini.2014_old';
my $find=' sql7.0.1 ';
my $replace = ' sqls715 ';

{
   local @ARGV =($filename);
   local $^I ='.bac';
   while (<>) {
      if (s/$find/$replace/ig) {
         print;
      } else {
         print;
      }
   }
}
print "Finished\n";

(after the $filename is verified)

XmTextReplace(3X)														 XmTextReplace(3X)

NAME
XmTextReplace - A Text function that replaces part of a text string SYNOPSIS
#include <Xm/Text.h> void XmTextReplace (widget, from_pos, to_pos, value) Widget widget; XmTextPosition from_pos; XmTextPosition to_pos; char * value; DESCRIPTION
XmTextReplace replaces part of the text string in the Text widget. The character positions begin at zero and are numbered sequentially from the beginning of the text. An example text replacement would be to replace the second and third characters in the text string. To accomplish this, the parameter from_pos must be 1 and to_pos must be 3. To insert a string after the fourth character, both parameters, from_pos and to_pos, must be 4. This routine calls the widget's XmNvalueChangedCallback and verification callbacks, either XmNmodifyVerifyCallback or XmNmodifyVerifyCall- backWcs, or both. If both verification callback lists are registered, the procedures of the XmNmodifyVerifyCallback list are executed first and the resulting data is passed to the XmNmodifyVerifyCallbackWcs callbacks. Specifies the Text widget ID Specifies the start posi- tion of the text to be replaced Specifies the end position of the text to be replaced Specifies the character string value to be added to the text widget For a complete definition of Text and its associated resources, see XmText(3X).
