What's wrong with this SQL statement?

Hi,

I'm trying to write an SQL Stored procedure and want to use arrays.
I've found examples on IBM sites for the following...

CREATE TYPE BIGINTARRAY AS BIGINT ARRAY[INTEGER];

and

CREATE TYPE CHARARRAY  AS CHAR(10) ARRAY[VARCHAR(3)];

It doesn't like the Integer type or the VARCHAR typingm with following message...
Position 41 Token INTEGER was not valid. Valid tokens: ].

Apparently Stored Procedures don't like arrays on i/OS (v7r3)?
How can I use arrays in SQL/PSM?
