It uses associative arrays, to understand how associative arrays work in awk, see this post https://www.unix.com/unix-dummies-que...wk-arrays.html

About running this awk script, you have to use it in the same way as he coded, its as per your requirements, if you don't know how to run it at command line, then put it in some shell-script and run that file. Something like this:
Code:
#! /bin/ksh
awk '{ arr[length($1)]++; arr[length($2)]++; }
       END {print "8 - 9 bytes", arr[8]+arr[9], " 10 bytes ", arr[10] } ' file

Save this shell-script as "test" then do the following:
Code:
chmod +x test
./test

PX_RETRIEVE_RECORD(3)													     PX_RETRIEVE_RECORD(3)

px_retrieve_record - Returns record of paradox database

SYNOPSIS
array px_retrieve_record (resource $pxdoc, int $num, [int $mode]) DESCRIPTION
This function is very similar to px_get_record(3) but uses internally a different approach to retrieve the data. It relies on pxlib for reading each single field value, which usually results in support for more field types. Note This function is only available if pxlib >= 0.6.0 is used. PARAMETERS
o $pxdoc - Resource identifier of the paradox database as returned by px_new(3). o $num - The record number is an artificial number counting records in the order as they are stored in the database. The first record has number 0. o $mode - The optional $mode can be PX_KEYTOLOWER or PX_KEYTOUPPER in order to convert the keys into lower or upper case. If $mode is not passed or is 0, then the key will be exactly like the field name. The element values will contain the field values. NULL values will be retained and are different from 0.0, 0 or the empty string. Fields of type PX_FIELD_TIME will be returned as an integer counting the number of milliseconds starting at midnight. A timestamp is a floating point value also counting milliseconds start- ing at the beginning of julian calendar. RETURN VALUES
Returns the $num'th record from the paradox database. The record is returned as an associated array with its keys being the field names. SEE ALSO
