Hi John,

Really thanks for your explanation and the reasons behind the decision
of change.
If it were in the Mathematica documentation, it would be excellent.

I just want to highlight in one sentence on your suggestion which
works for me.

<< Version5`Graphics`
before plot commands to get older vector metafile as found in
Mathematica 5.2

This method allows me to regain the older Mathematica way to generate
vector metafile.
Hope it will help other Mathematica users when they run into the same
questions.

Thanks again, John.

Lawrence
