sed optimized for replace substring

Hi All,
I have this text file

Code:
 IR7013903069171012INT10171211864
 Axxxxxxxxxx12345dddddddddddd
 Byyyyyyyyy99999999ddddddddd
 IR7013903069171012TOS10171211865
 Cffffffffff5745747ehdefffffffffgggggggg
 Dyyyyyyyyy99999999ddddddddd

I need to
1) find lines where the substring IR70139 is present
2) only in the lines selected by the point 1, I need to replace the substring INT and TOS by SFD

I have used this command

Code:
cat <input filename>| grep IR70139 | sed s/INT/SFD/  > output_file

Is there a better command line to execute my command?

For example
Code:
sed /search string1/,/search string2/ {  s/INT/SFD/  s/TOS/SFD/ } < inputfile > outputfile

I have tried but without success.

Any help will be well appreciated.

Thanks in advance for your kind support.

Regards,

Giovanni

NAME
Locale::Codes::LangExt - standard codes for language extension identification SYNOPSIS
use Locale::Codes::LangExt; $lext = code2langext('acm'); # $lext gets 'Mesopotamian Arabic' $code = langext2code('Mesopotamian Arabic'); # $code gets 'acm' @codes = all_langext_codes(); @names = all_langext_names(); DESCRIPTION
The "Locale::Codes::LangExt" module provides access to standard codes used for identifying language extensions, such as those as defined in the IANA language registry. Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default IANA language registry codes will be used. SUPPORTED CODE SETS
There are several different code sets you can use for identifying language extensions. A code set may be specified using either a name, or a constant that is automatically exported by this module. For example, the two are equivalent: $lext = code2langext('acm','alpha'); $lext = code2langext('acm',LOCALE_LANGEXT_ALPHA); The codesets currently supported are: alpha This is the set of three-letter (lowercase) codes from the IANA language registry, such as 'acm' for Mesopotamian Arabic. This is the default code set. ROUTINES
code2langext ( CODE [,CODESET] ) langext2code ( NAME [,CODESET] ) langext_code2code ( CODE ,CODESET ,CODESET2 ) all_langext_codes ( [CODESET] ) all_langext_names ( [CODESET] ) Locale::Codes::LangExt::rename_langext ( CODE ,NEW_NAME [,CODESET] ) Locale::Codes::LangExt::add_langext ( CODE ,NAME [,CODESET] ) Locale::Codes::LangExt::delete_langext ( CODE [,CODESET] ) Locale::Codes::LangExt::add_langext_alias ( NAME ,NEW_NAME ) Locale::Codes::LangExt::delete_langext_alias ( NAME ) Locale::Codes::LangExt::rename_langext_code ( CODE ,NEW_CODE [,CODESET] ) Locale::Codes::LangExt::add_langext_code_alias ( CODE ,NEW_CODE [,CODESET] ) Locale::Codes::LangExt::delete_langext_code_alias ( CODE [,CODESET] ) These routines are all documented in the Locale::Codes::API man page.
