urgent : stored procedure not accepting data string more than 1024 bytes

[Roger]

have a stored procedure running on DB2 V7 Z/os calling a COBOL
program to do some inserts. The stored procedure have 3 input columns
and one column is of varchar(32648)
The stored procedure is being called from a V7 DB2 connect client.

The stored procedure is giving SQL0104N An unexpected token was found
if my varchar data goes beyond 1024 bytes. Anything under 1025 bytes
on that column is working perfectly.
Does anybody know of any limitation of Stored procedure.

here is the stored procedure

CREATE PROCECURE CUSTOMSP

,IN CUSTOMER_NO CHAR(10)
,IN ORD_NO CHAR(8)
,IN ENCODED_DATA VARCHAR(32648)
,OUT WSRETURN INT
