Re: ODBC exit point program

[MBarton@xxxxxxxxxx]

Hi
     I am having problems with a (seemingly) simple program to validate
ODBC
requests via the ODBC exit point
QIBM_QZDA_ROI1        ZDAR0100 format

I chose ZDAR0100 (object information) rather than ZDAQ01/200 as I don't
want to have
to parse the SQL statement.
The ZDAR0100 appears to have the file & library that in set positions.

My program checks through a data-base file for valid library/file names
before deciding
to accept/reject the request.

All seems to work ok in that the Reject message is sent to QSYSOPR,
but the request is allowed despite my program returning a parameter
of '0'. Dumping the program at ths point shows value '0' (reject).

I can only assume that something is over-writing the variable somewhere.

Someone suggested that when adding the exit program I should specify
the PGMDTA parameter to be the length I am expecting in my program
but this seems to make no difference.

We are on V4R5
