Ok, hello


I'm trying to make a simple comunication interface between dotty (with 
modifying lefty script) and a single c program.

I dont understand anything about the documentation ant this dont works :-(

If i do in my lefty script

tub = openio ('pipe', 'more', "w");
dotty.message (tub,'muchas gracias');

is only a probe but /bin/more should show "muchas gracias"... no?

I dont know where, how and who creates the pipe, who gets the reading 
and who the writing and why...

I tried in my C program to create the pipe and do to the invoking 
program... without succes...

please
anybody can help me?
