JJ,

So, I entered, on a commandline, the following: "one foo=bar".

My apologies, as I see that I somehow left the word "echo" out in the body
of the message, and placed the double-quotes wrong in the subjectline. :-(

The full commandline I used is (without the doublequotes ofcourse) "echo one
foo=bar"

This exact command line:

echo "one foo=bar"

:-) /allmost/ the same one.

Two reasons:
1. The "=" character is treated as delimiters.
2. CMD processes redirection syntax first.

Thus the command line:

echo one foo=bar

CMD recognizes the " foo" syntax as redirection. It stops before the "="
delimiter. Then strips it out from the command line. After the redirection
has been processed, the command line becomes:

echo one =bar

Then that "one =bar" is outputed.

This is similar case when there's a file named "foo=bar" and below command
line is executed.

dir foo=bar

That ends up making DIR listing two files: "foo" and "bar". It's output
would be like this.

Notice that it shows two "Directory of..." lines, instead of one.
