\presentationstep not working?

\presentationstep not working?

[Otared Kavian]

Dear all,

I am trying to use the macros packages written by Hans in ConTeXt for 
presentation of slides on a computer. Indeed the styles written by Hans 
are wonderful, but I could not use the command \presentationstep 
defined in the style "s-pre-00.tex", and went on to find help on the 
web.

I found that Michael Guravage has had the same difficulty in 1999, 
about three years ago, and that Hans Hagen has given him a solution. 
However by doing what Hans suggested in December 1999, I could not 
either solve the difficulty.
Could anyone please tell me whether there is a way to implement the 
command "\step" in PDF presentations using ConTeXt?
Does anyone have an example file which has really worked and could send 
me?

To be complete, I should say that I am using Mac OS X, version 10.1.5, 
TeXShop version 1.20 (written by Richard Koch with Dirk Olmes and 
Gerben Wierda), and the teTeX package maintained by Gerben Wierda which 
includes ConTeXt, version 2002.08.23, and finally Acrobat Readrer 5.0.

Thanks for your help.
Cheers: Otared K.
