(If i understand your question):
If your first bloc is false, your second is execute, this is like:
Code:
$ cat te_ak

XX_2_YY
XX_3_YY
XX_4_YY
XX_5_YY
XX_6_YY
XX_7_YY
XX_8_YY
XX_9_YY
XX_10_YY
$ awk -F_ 'code[$1_$2]{ print }; END{ for (i in code) print "code[" i "]=" code[i]} ' te_ak 
code[XX9]=
code[XX1]=
code[XX2]=
code[XX3]=
code[XX4]=
code[XX5]=
code[XX10]=
code[XX6]=

ExtUtils::Typemaps::OutputMap(3pm)			 Perl Programmers Reference Guide			ExtUtils::Typemaps::OutputMap(3pm)

NAME
ExtUtils::Typemaps::OutputMap - Entry in the OUTPUT section of a typemap SYNOPSIS
use ExtUtils::Typemaps; ... my $output = $typemap->get_output_map('T_NV'); my $code = $output->code(); $output->code("..."); DESCRIPTION
Refer to ExtUtils::Typemaps for details. METHODS
new Requires "xstype" and "code" parameters. code Returns or sets the OUTPUT mapping code for this entry. xstype Returns the name of the XS type of the OUTPUT map. cleaned_code Returns a cleaned-up copy of the code to which certain transformations have been applied to make it more ANSI compliant. targetable This is an obscure optimization that used to live in "ExtUtils::ParseXS" directly. In a nutshell, this will check whether the output code involves calling "set_iv", "set_uv", "set_nv", "set_pv" or "set_pvn" to set the special $arg placeholder to a new value AT THE END OF THE OUTPUT CODE. If that is the case, the code is eligible for using the "TARG"-related macros to optimize this. Thus the name of the method: "targetable". If the optimization can not be applied, this returns undef. If it can be applied, this method returns a hash reference containing the following information: type: Any of the characters i, u, n, p with_size: Bool indicating whether this is the sv_setpvn variant what: The code that actually evaluates to the output scalar what_size: If "with_size", this has the string length (as code, not constant) SEE ALSO
