ENVIRON is an array provided by awk that stores the environment variables. each element of the array is the value in your current environment and the index is the name of the environment variable
so ENVIRON["DUP"] will give the path of the DUP environment variable in your machine. It may hapen that DUP does not exists in some machines.
try this to see what all environment variables exits in your system and then you will understand what the above code does
awk 'BEGIN{for (env in ENVIRON)print env "=" ENVIRON[env]}'

wsdup
wstring(3C) Standard C Library Functions wstring(3C)NAME
wstring, wscasecmp, wsncasecmp, wsdup, wscol - Process Code string operations
SYNOPSIS
#include <widec.h>
int wscasecmp(const wchar_t *s1, const wchar_t *s2);
int wsncasecmp(const wchar_t *s1, const wchar_t *s2, int n);
wchar_t *wsdup(const wchar_t *s);
int wscol(const wchar_t *s);
DESCRIPTION
These functions operate on Process Code strings terminated by wchar_t null characters. During appending or copying, these routines do not
check for an overflow condition of the receiving string. In the following, s, s1, and s2 point to Process Code strings terminated by a
wchar_t null.
wscasecmp(), wsncasecmp()
The wscasecmp() function compares its arguments, ignoring case, and returns an integer greater than, equal to, or less than 0, depending
upon whether s1 is lexicographically greater than, equal to, or less than s2. It makes the same comparison but compares at most n Process
Code characters. The four Extended Unix Code (EUC) codesets are ordered from lowest to highest as 0, 2, 3, 1 when characters from different
codesets are compared.
wsdup()
The wsdup() function returns a pointer to a new Process Code string, which is a duplicate of the string pointed to by s. The space for the
new string is obtained using malloc(3C). If the new string cannot be created, a null pointer is returned.
wscol()
The wscol() function returns the screen display width (in columns) of the Process Code string s.
