#Please describe what is going on here.
$names{"$first,$last"}={count => ++$count{"$first,$last"},
name => "$first $mi $last $state",
};
I'll try....
$names{"$first,$last"} creates a hash key from the first and last name.
its' value is in turn a hash:
the "count" keys value is the value of another hash: %count, which is keeping count of how many times the first,last names are found:
so we can determine later if it is a unique combination or not. If it has a count of 1 (one) then it is unique.
the "name" keys is just the original line from the file which we use to print to the output file if the value of the "count" key is 1 (one).
You can uncomment the lines that say to "uncomment for debugging" and you will see the data structure of %names printed when the script finishes running.

px_get_info
PX_GET_INFO(3)PX_GET_INFO(3)px_get_info - Return lots of information about a paradox fileSYNOPSIS
array px_get_info (resource $pxdoc)
DESCRIPTION PARAMETERS
o $pxdoc
- Resource identifier of the paradox database as returned by px_new(3).
RETURN VALUES
Returns an associated array with lots of information about a paradox file. This array is likely to be extended in the future.
o fileversion
-Version of file multiplied by 10, e.g. 70.
o tablename
-Name of table as stored in the file. If the database was created by pxlib, then this will be the name of the file without the
extension.
o numrecords
-Number of records in this table.
o numfields
-Number of fields in this table.
o headersize
-Number of bytes used for the header. This is usually 0x800.
o recordsize
-Number of bytes used for each record. This is the sum of all field sizes (available since version 1.4.2).
o maxtablesize
- This value multiplied by 0x400 is the size of a data block in bytes. The maximum number of records in a datablock is the integer
part of (maxtablesize * 0x400 - 8) / recordsize.
o numdatablocks
- The number of data blocks in the file. Each data block contains a certain number of records which depends on the record size and
the data block size (maxtablesize). Data blocks may not necessarily be completely filled.
o numindexfields
- Number of fields used for the primary index. The fields do always start with field number 1.
o codepage
- The DOS codepage which was used for encoding fields with character data. If the target encoding is not set with px_set_targeten-
coding(3) this will be the encoding for character fields when records are being accessed with px_get_record(3) or
px_retrieve_record(3).
