Demonstrate that the CGIplus::var() function and $ENV associative array contents are identical ...

$ENV{'SCRIPT_NAME'}  |/cgi-bin/CGIplusPM_example1.pl|
CGIplus::var('SCRIPT_NAME')  |/cgi-bin/CGIplusPM_example1.pl|

$ENV{'PATH_INFO'}    |/wasd_root/src/perl|
CGIplus::var('PATH_INFO'}    |/wasd_root/src/perl|

$ENV{'QUERY_STRING'} ||
CGIplus::var('QUERY_STRING') ||

SERVER_SOFT does not exist and looks like an empty string ...
SERVER_SOFT ||

SERVER_SOFTWARE should exist ...
