XMetaL3: restrict opened files to only one?

[stefan.kirchberger]

Hello,

I have a question about Softquad XMetaL3: is it possible to restrict
the numbers of files opened to only one at the the time (and to prevent
users to load a second or a third file)? I've been searching through
all the help, documentation, found nothing in xmetal.ini... maybe one
knows how.

Thank you,
Stefan Kirchberger
