If I make the DIM bigger than 1000000 (say 16000000 )I get a compile

Presumably this is the upper limit for the sum of the parameters passed ?
Thanks for your help everyone .... what a great forum !

I've just tried changing the return value from JDBC_GetCol() to
16Mb (my IDE was telling me that 65535 was the limit .. shows how old
it is) but it saved and compiled ok. However it still only returns
32767 bytes of XML in the 16Mb field, which suggests that's all JDBC is returning.
(statement result = r(str); in the JDBC_getCol() procedure
listed below).
I downloaded the Microsoft JDBC Driver 4.0 for SQL Server last month,
so maybe it's a bit behind the iSeries JRE 1.6.0 I'm not sure where to
go from here ... but probably not a suitable post for an RPG forum ...
unless anybody knows ?

While wrappers are nice as the make things simpler; the price you pay
for simplicity is less flexibility and accepting new limits.
You're going to need to write your own JDBC_GetCol() using Scott's as
a guide that handles results bigger than 32K.
RPGLE at 6.1+ allows for ~16MB. You could basically copy the existing
proc change the size of the return value and result variable and call
it
JDBC_GetCol16MB()
or something. Be sure to pass your changes back to scott and he can
possibly incorporate them into the distribution. To make it easier,
you should probably wrap your new proc and prototype in an /IF DEFINED(*V6R1M0).
If that's not enough, you'd probably need to look at taking advantage
of teraspace.

So .. I tried using JDBC in and RPGLE program using JNI. My
as shown below.and delete the material from any computer.
The program works fine when the content is less than 32767 but fails
on the XML-INTO when its bigger (RNX0353 reason 5)
Can anyone point me in the right direction ?
I should add we are running V7R1.
