Yes, I completely agree with you. On the other hand, I think that one  
thing which still lacks in Nisus macro language is the possibility of  
using sub-routine. When this will be possible, I think/hope that  
writing macros will be much simpler (but before that, we -- I --  
should master the current macro language, which is not easy at all...!).

Ah, I would have not been able to find this by myself. Very  
intelligent and helpful!

This is also very useful. It seems there are many interesting and  
useful commands in the macro language, but it is difficult to  
understand and use them when one is not familiar with it. Exercise  
and experience...!

This version is much simpler and cleverer. Thank you very much. I  
will keep it in my macro file.

I will reply to your other posting, and please wait some time...
