Re: Updating file via datastructure

That quote IS in the V5R3M0 manual with change bars next to it.

In addition, the V5R2M0 manual explicitly states.

2) "...data-structure cannot be specified if name is a record format name."

Are you sure you weren't reading/quoting the V5R3M0 manual?

Hi Mel

Point 2 I had covered but point 1 is odd as it states in the V5R2 reference
manual, operation code "UPDATE":

<Quote>
If the data-structure operand is specified, the record is updated directly
from the data structure.
....
If name refers to an externally-described file, the data structure must be a
data structure defined with EXTNAME(...:*INPUT) or LIKEREC(...:*INPUT). The
updated record is written directly from the data structure to the file.
...
<Unquote>

Or are you referring here to the overlay part of the datastructure. I.e.
data structures with overlays are not supported until V5R3?

Thanks for you help.

In addition to the previous suggestion about defining the array as
overlaying the data structure:

1) Using a data structure for UPDATE with an externally described file was
not supported by the language until V5R3M0.

2) It also requires that the data structure be defined with
EXTNAME(...:*INPUT) or LIKEREC(...:*INPUT). If the parameter where *INPUT would be specified is

missing, the compiler defaults to *INPUT, so that probably is not your
problem.

I hope this helps.

Hi Joep

Thanks for you reply.

I tried your suggestion and the compiler stoped with the same error.
I changed the code to

DDSHISTRC E DS EXTName(SHISTRCL1) D RM 3P 0 OVERLAY(DSHISTRC:72) DIM(24)

and it still gave the same problem.

According to the manual this should not be a problem.

Thanks

Tilo

Hi Tilo,

IIRC the field Record is added to the datastructure, thus making the datastructure longer than the record. You should add OVERLAY(DSHISTRC) to
the Record field.

Hi

I am trying to update a file using a datastructure because I want to

update

24 fields on the file as an array

D*

When I try to update the file using the following command:

       UPDATE RISREC DSHISTRC;

the compiler gives the following error message:

*RNF7701 20 The data structure is not allowed for the operation.

What am I doing wrong?
