MPcode inserts page

MPcode inserts page

[Henning Hraban Ramm]

Hi, if I use \startMPcode to declare variables etc. that I need in 
several MP graphics, it always inserts an empty page. How can I avoid that?
(Actually, I load an external mp file, and for random value reasons I 
must load it only once. But the MWE already shows the problem.)


"""
\startMPcode
numeric something;
something := 1;
\stopMPcode

\starttext
\chapter{Something}

Anything.

\stoptext
"""

\startMPinitializations % used by ALL MP instances
% also called repeatedly
\stopMPinitializations

\startMPdefinitions
\stopMPdefinitions

This is what you want.

Exactly, the latter.
Thank you, these two environments were missing in my book.
