 Mark & All Memers, 

        How does one interupt this ;

max_descriptor 
(Input) Descriptors are numbered starting at zero, so the max_descriptor 
parameter must specify a value that is one greater than the largest
descriptor number that is to be tested. 

        In a select(max_descriptor, read_sl, write_sl, excpt_sl, time_out);

        Is this the one greater than the number of discriptors in the 
three select lists, or one greater than the largest value returned by
any function that assigns a handle in the ?? 
(stack/module/program/activation group). Or is there some other 
definition I am missing here ??

        Thanks, 
        Jeff Silberberg
