clarification of question
That 10th position that's being replaced need not be a G. Strictly speaking, it could be anything. That's why I show it as being either a G or a C in the three examples I put up. Unfortunately, G's and C's look similar. Maybe I should have made that a "C or T" or a "G or A" (those are the actual options for what I'm doing).

Also, the data at OTHER points in each string is ALSO not identical.

If I remember correctly, I can put two options in brackets at that location, and otherwise follow what you're suggesting. Or whatever the symbol for a single character wild card is, which I should be able to look up. I remember that it's not just an asterisk (*).

Would this work?

Code:
echo "AAAA[AT]TAAA[ACGT]AAAA"| awk '{substr((sub(/[ACGT]/,"N")),10,1); print}'



Thanks!

NB, I also don't understand the comment about code tags, because so far as I know, I have not included any code, and my example is not "data," it's an explanation of my terminology, in case I'm using my terms incorrectly. Perhaps "data" means something different to a computer scientist than it does to a biologist. Apologies, if so.

locale::currency

Locale::Currency(3perl) 				 Perl Programmers Reference Guide				   Locale::Currency(3perl)

NAME

       Locale::Currency - standard codes for currency identification

SYNOPSIS

	   use Locale::Currency;

	   $curr = code2currency('usd');     # $curr gets 'US Dollar'
	   $code = currency2code('Euro');    # $code gets 'eur'

	   @codes   = all_currency_codes();
	   @names   = all_currency_names();

DESCRIPTION

       The "Locale::Currency" module provides access to standard codes used for identifying currencies and funds, such as those defined in ISO
       4217.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 4217
       three-letter codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying currencies. The ones currently supported are:

       alpha
	   This is a set of three-letter (uppercase) codes from ISO 4217 such as EUR for Euro.

	   Two of the codes specified by the standard (XTS which is reserved for testing purposes and XXX which is for transactions where no
	   currency is involved) are omitted.

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

	   This is the default code set.

       num This is the set of three-digit numeric codes from ISO 4217.

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

ROUTINES

       code2currency ( CODE [,CODESET] )
       currency2code ( NAME [,CODESET] )
       currency_code2code ( CODE ,CODESET ,CODESET2 )
       all_currency_codes ( [CODESET] )
       all_currency_names ( [CODESET] )
       Locale::Currency::rename_currency  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Currency::add_currency  ( CODE ,NAME [,CODESET] )
       Locale::Currency::delete_currency  ( CODE [,CODESET] )
       Locale::Currency::add_currency_alias  ( NAME ,NEW_NAME )
       Locale::Currency::delete_currency_alias	( NAME )
       Locale::Currency::rename_currency_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Currency::add_currency_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Currency::delete_currency_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes man page.
