Hey , I can already do it !

I have a recent cvs build , I just thought this was still in long term 
future planning. Brilliant.

I see it is under 'help do' but not 'help for'.

gnuplot> help for
Ambiguous request 'for'; possible matches:
         format
         fortran

Probably helpful to include it there too.

Thanks to the team for including this already , this opens up a word of 
possibilities.
thanks Péter for bringing me upto date.

Is there any overall documentation for the new block structures or do I 
have to guess the keywords to get individual syntax?


regards, Peter.
