You said,
Quote:
(s/^\s*//, s/\s*$//) for ($first,$mi,$last,$state);
That part actually removes leading and trailing spaces from the list of variables.
I am crystal clear with this clarification. Thanks.

However, the hash structure you used
Code:
$names{"$first,$last"}={count => ++$count{"$first,$last"},
name => "$first $mi $last $state",
};

is so compact and does so much, that even with your description, it remains beyond my full grasp at this stage of my perl newbishness.

Even though I don't fully grasp this data structure, I can use it, modify it, and apply it. So thanks again KevinADC!

wsreg_query_get_unique_name

wsreg_query_set_unique_name(3WSREG)		    Product Install Registry Library Functions		       wsreg_query_set_unique_name(3WSREG)

NAME

       wsreg_query_set_unique_name, wsreg_query_get_unique_name - set or get the unique name of a query

SYNOPSIS

       cc [flag ...]  file ...-lwsreg [library ...]
       #include <wsreg.h>

       int wsreg_query_set_unique_name(Wsreg_query *query, const char *unique_name);

       char *wsreg_query_get_unique_name(const Wsreg_query *query);

DESCRIPTION

       The wsreg_query_set_unique_name() function sets the unique name specified by unique_name in the query specified by query.  If a unique name
       has already been set in the specified query, the resources associated with the previously set unique name are released.

       The wsreg_query_get_unique_name() function gets the unique name string from the query specified by query.  The resulting string	is  not  a
       copy and must not be released by the caller.

RETURN VALUES

       The wsreg_query_set_unique_name() function returns a non-zero value if the unique_name was set correctly; otherwise 0 is returned.

       The wsreg_query_get_unique_name() function returns a copy of the unique_name from the specified query.

USAGE

       The  query  identifies  fields used to search for a specific component in the product install registry.	By specifying the unique name, the
       component search is narrowed to all components in the product install registry that have the specified unique name.

       Other fields can be specified in the same query to further narrow the search.
