hello everybody Smile

i can't get it:

T = ets:new( data, [set] ),
ets:insert( T, {a,1} ).

is working ok but

ets:new( data, [set] ),
ets:insert( data, {a,1} ).

gives me badarg.

why is that? is not "data" atom used for identifying the table?

thanks!

Hi,
You will need to pass on named_table option so that the name will be associated with the table identifier. Read here http://www.erlang.org/doc/man/ets.html#new/2 and try this:

ets:new( data, [set, named_table]).
