thanks for the ascii-mail.
but please reply not only to me but to the whole list. other people 
might be interested as well.

i see.

i am still not sure what you want to achieve in the first place:
i can think of 2 possibilities:
a) each time you get a value from [netserver] you write this value to 
the table and increment the index by one ("asynchronous"); after the 
table is full you re-start at the beginning
i guess this is not what you want
b) a counter increments the index according to a reference clock. 
whenever a value comes in from [netserver] it is inserted at the 
"correct" place in the table ("synchronous"); i guess this is more what 
you want.



your patch does following:
a new value comes in
you start a clocked index-counter ([metro]) that counts *quite fast* 
(but *not* immediatly) from 0.
"in the meanwhile" you send the "value" to the first inlet of the 
[tabwrite]; as the index (2nd inlet) happens to be 0, you write this 
value into the first element of the array.
the counter continues to increment the index each dsp-tick (the "grain" 
of pd's message system) until it reaches 256 and then stops.
if nothing comes in in this time (1.3ms*256) the result would be:
the value is stored in the first element of the table; the rest of the 
table is untouched.
if a value arives while the counter is still counting, this value will 
be inserted at the "current" index (which is a function of time but 
looks rather random)




what is going wrong ? your index-counter does not behave well (i think, 
but of course i might be wrong)

for scenario-a use something like

|
[t f b] _______
|     | |     |
|     [i]     |
|     |       |
|     [+ 1]   |
|     |       |
|     [% 256] |
|     |_______|
|     |
[tabwrite bla]


for scenario-b you should detach the clock of the counter entirely from 
your input values.
and just as a tip, try to make the index the "master" that defines the 
time, when a new value is inserted.
and why do you run metro at full speed ?

[i]/[+ 1]/[% 256]

oh, i tried to not give the full solution...
