sed variable expansion fails for substitution in range
I'm trying to change "F" to "G" in lines after the first one:
Code:
'FUE.SER' 5
 1  1             F0501 F0401 F0502
 2  1       F0301 E0501 F0201 E0502 F0302
 3  1 F0503 E0503 E0301 E0201 E0302 E0504 F0504
 4  1 F0402 F0202 E0202 F0101 E0203 F0203 F0403
 5  1 F0505 E0505 E0303 E0204 E0304 E0506 F0506
 6  1       F0303 E0507 F0204 E0508 F0304
 7  1             F0507 F0404 F0508
 0  0

This is the desired end state:
Code:
'FUE.SER' 5
 1  1             G0501 G0401 G0502
 2  1       G0301 E0501 G0201 E0502 G0302
 3  1 G0503 E0503 E0301 E0201 E0302 E0504 G0504
 4  1 G0402 G0202 E0202 G0101 E0203 G0203 G0403
 5  1 G0505 E0505 E0303 E0204 E0304 E0506 G0506
 6  1       G0303 E0507 G0204 E0508 G0304
 7  1             G0507 G0404 G0508
 0  0

Here's the script:

Code:
#!/bin/sh -xv
AAA=G
sed -e '/FUE\.SER/,/0  0/ {/FUE\.SER/b; s/F/'$AAA'/g;}'

Here's the output:

Code:
'FUE.SER' 5
0502 G            G
0302 E0502 GG
0504 E0503 E0301 E0201 E0302 E0504 G
0403 G0203 G
0506 E0505 E0303 E0204 E0304 E0506 G
0304 E0508 GG
0508 G            G
 0  0

I've tried several different quote schemes but can't seem to get $AAA to substitute correctly. Anyone have any suggestions?
Thanks,
Larry

locale::codes::langvar

Locale::Codes::LangVar(3)				User Contributed Perl Documentation				 Locale::Codes::LangVar(3)

NAME

       Locale::Codes::LangVar - standard codes for language variation identification

SYNOPSIS

	  use Locale::Codes::LangVar;

	  $lvar = code2langvar('acm');		       # $lvar gets 'Mesopotamian Arabic'
	  $code = langvar2code('Mesopotamian Arabic'); # $code gets 'acm'

	  @codes   = all_langvar_codes();
	  @names   = all_langvar_names();

DESCRIPTION

       The "Locale::Codes::LangVar" module provides access to standard codes used for identifying language variations, 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 variations. 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:

	  $lvar = code2langvar('arevela','alpha');
	  $lvar = code2langvar('arevela',LOCALE_LANGVAR_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of alphanumeric codes from the IANA language registry, such as 'arevela' for Eastern Armenian.

	   This code set is identified with the symbol "LOCALE_LANGVAR_ALPHA".

	   This is the default code set.

ROUTINES

       code2langvar ( CODE [,CODESET] )
       langvar2code ( NAME [,CODESET] )
       langvar_code2code ( CODE ,CODESET ,CODESET2 )
       all_langvar_codes ( [CODESET] )
       all_langvar_names ( [CODESET] )
       Locale::Codes::LangVar::rename_langvar  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangVar::add_langvar  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangVar::delete_langvar  ( CODE [,CODESET] )
       Locale::Codes::LangVar::add_langvar_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangVar::delete_langvar_alias  ( NAME )
       Locale::Codes::LangVar::rename_langvar_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangVar::add_langvar_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangVar::delete_langvar_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
