Gustavo,

I don't know about Pascal's read() - 10 years ago for me, sorry -
but I guess you want to reach the content of a DOS environment variable
defined like "SET  WINDIR=C:\WINNT".
You could do it like this:

String tempfile = "c:\\temp\\x.txt";
Runtime.getRuntime().exec( "command.com /c set > " + tempfile );
File file = new File( tempfile );
InputStream input = new FileInputStream( file );
Properties prop = new Properties();
prop.load( input );
input.close();
file.deleteOnExit();

This all must be in a try-Block and catch IOException.

You can get the content of each DOS variable now like prop.getProperty(
"WINDIR" );

Just try with the case sensivity. Your variable might be defined as "windir"
or "Windir" etc. - DOS doesn't care, but Properties class does.

Of course - from Java sight I must say this is a very ugly solution!
But for DOS' and Windows' environment variables that might be adequate. :-)
This code is not portable, and you need a temporary file. Though you delete
it afterwards, it could have existed already, so you ruin it. If you have
bad luck you won't be permitted to write to it.
I tried to get the output of the executed DOS-command directly into an
InputStream, but didn't succeed in that short time.

Regards,
Hartmut
