The solution to my question is the command
do EXPR;
, having as EXPR the script-2!

That way the script-2 will have defined in script-1 some variables;
it will process everything, printing on STDOUT what it should print (the script-2), and
it will set any variable that will be available in the script-1 after completing the script-2.

After finishing the script-2 control coming back to script-1

That is all I been looking for!

(Hmm, after review my question, surprizingly realizing that I have used the 'do ..'
How it happening that I have mislead myself to have it not enough, I am not sure!
--- My apologizes for all that mess!!!! )

perl-after-upgrade

PERL-AFTER-UPGRADE(1)					User Contributed Perl Documentation				     PERL-AFTER-UPGRADE(1)

NAME

       perl-after-upgrade -- fixup FreeBSD packages that depend on perl

SYNOPSIS

	 perl-after-upgrade
	 perl-after-upgrade -f
	 perl-after-upgrade -v

DESCRIPTION

       The standard procedure after a perl port (either lang/perl5.6 or lang/perl5.8) upgrade is to basically reinstall all other packages that
       depend on perl.	This is always a painful exercise.  The perl-after-upgrade utility makes this process mostly unnecessary.

       The tool goes through the list of installed packages, looks for those that depend on perl, moves files around, modifies shebang lines in
       those scripts in which it is necessary to do so, tries its best to adjust dynamically linked binaries that link with libperl.so in the old
       path, and updates the package database.

       After installation of the new perl is complete, either by hand from the ports collection, or from a package, or via portupgrade, do the
       following:

       o go root;
       o run perl-after-upgrade utility.
	   Do not specify any arguments at first, so it does nothing destructive.  Pay attention to the produced output and especially to
	   errorlist at the end, if any;

       o run the utility again, with -f command line option.
	   This will actually do the work.  Again, pay attention to the output produced;

       o fix any reported errors;
       o reinstall required packages:
	   The utility will tell you what packages that depend on perl it could not handle.  It will also tell you why it happened (for example,
	   they were compiled against a binary incompatible perl).  If you want such packages to remain operational, you will have to reinstall
	   then by hand or via portupgrade.

       o review the files left in the older perl installation.
	   This is typically /usr/local/lib/perl5/site_perl/5.X.Y/.  There should be very little, if any, files in that directory and its subdi-
	   rectories, excepting a number of .ph files;

       o check that things work as they should;
       o remove backup files from the package database.
	   Those will be /var/db/pkg/*/+CONTENTS.bak;

       o that's all.
