Hello Maarten,
once again thanks for your help. Unfortunately your suggestion did not help to solve the problem since the homepage you posted is exactly the site from which the ado-file was actually obtained-just for your information.
Thank you,
Jochen

Betreff: Re: st: problem with the inteff command
I vaguely remember that that problem got solved when the latest version
of -inteff- was installed, which can be downloaded from Edward Norton's
website: http://www.unc.edu/%7Eenorton/
Hope this helps,
Maarten
