DB2 on AIX:  Error when creating trigger that calls a stored procedure

I am working with DB2 8.1 on AIX 5.2.  I am trying to call a stored procedure from a trigger.  The trigger is written in SQL.  The stored procedure is declared in SQL and defined as an external routine in C.  The declarations are as follows:

create procedure testschema.proc_test (in chat_id char(96), in in_clob clob)
dynamic result sets 0
language c
parameter style general
fenced not threadsafe
modifies sql data
program type sub
external name 'proc_test!proc_test'@

create trigger testschema.proc_test
after
insert on testschema.w_chat_transcript
referencing new as n
for each row
begin atomic
  declare rs integer default 0;
  call testschema.proc_test (n.chat_id, n.transcript);
  get diagnostics rs = return_status;
  values (case when rs < 0 then raise_error ('70001', 'proc call failed'));
end@

I can catalog the stored proc just fine but when I go to catalog the trigger I get the following error:
DB21034E  The command was processed as an SQL statement because it was not a
valid Command Line Processor command.  During SQL processing it returned:
SQL0104N  An unexpected token "call" was found following "integer default 0;
".  Expected tokens may include:  "<compound_return>".  LINE NUMBER=8.  
SQLSTATE=42601

I have looked at many examples and they are all using the 'call' statement just as I am.  Any insight as to why I am seeing this error?

I am answering my own question.  DB2 8.2 is required to call a stored procedure from a trigger.
