I will have many files to process and all are the same format, and I will need to extract this line out, and then read the Center Number and name, then write them out to another file.

Another part of the script will read the input file and this part only needs to extract the Number and name from this line. The number wil be any number between 1 and 999, and the leading zero is the problem.

Your script writes:
Code:
D;003;100M Run;;M;;

into the file MM_file.txt from the last (not first) line of your input file FILE.EXT which you said contains:
Code:
"C 56","Home athletics center","LAC"
"D001","50M Run","50M"
"D003","100M Run","100M"

At various times you have said that the leading zeros are a problem and that the leading space is a problem. You have not shown us what output you want to be produced. My script processed each line in your input file, stripping off leading spaces and leading zeros and putting:
Code:
D;56;Home athletics center;;M;;
D;1;50M Run;;M;;
D;3;100M Run;;M;;

in MM_file.txtwhich is one line of output for each line of input. If this is not what you want, please explain clearly what output you do want in English and show us the output you want to have produced with the sample input file you provided. (Note that I see no way to get the output you showed in message #4 in this thread:
Code:
D;156 ;Home athletics center;;M;;

since 156 does not appear as a number on any of your sample input lines???)

locale::codes::script

Locale::Codes::Script(3pm)				 Perl Programmers Reference Guide				Locale::Codes::Script(3pm)

NAME

       Locale::Codes::Script - standard codes for script identification

SYNOPSIS

	  use Locale::Codes::Script;

	  $script  = code2script('phnx');		      # 'Phoenician'
	  $code    = script2code('Phoenician'); 	      # 'Phnx'
	  $code    = script2code('Phoenician',
				 LOCALE_CODE_NUMERIC);	      # 115

	  @codes   = all_script_codes();
	  @scripts = all_script_names();

DESCRIPTION

       The "Locale::Codes::Script" module provides access to standards codes used for identifying scripts, such as those defined in ISO 15924.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 15924
       four-letter codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying scripts. 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:

	  $script = code2script('phnx','alpha');
	  $script = code2script('phnx',LOCALE_SCRIPT_ALPHA);

       The codesets currently supported are:

       alpha, LOCALE_SCRIPT_ALPHA
	   This is a set of four-letter (capitalized) codes from ISO 15924 such as 'Phnx' for Phoenician.  It also includes additions to this set
	   included in the IANA language registry.

	   The Zxxx, Zyyy, and Zzzz codes are not used.

	   This is the default code set.

       num, LOCALE_SCRIPT_NUMERIC
	   This is a set of three-digit numeric codes from ISO 15924 such as 115 for Phoenician.

ROUTINES

       code2script ( CODE [,CODESET] )
       script2code ( NAME [,CODESET] )
       script_code2code ( CODE ,CODESET ,CODESET2 )
       all_script_codes ( [CODESET] )
       all_script_names ( [CODESET] )
       Locale::Codes::Script::rename_script  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::Script::add_script  ( CODE ,NAME [,CODESET] )
       Locale::Codes::Script::delete_script  ( CODE [,CODESET] )
       Locale::Codes::Script::add_script_alias	( NAME ,NEW_NAME )
       Locale::Codes::Script::delete_script_alias  ( NAME )
       Locale::Codes::Script::rename_script_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::Script::add_script_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::Script::delete_script_code_alias	( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
