newbe question: convert codepage

[Arben Qarkaxhija]

Hello all,

I'm new to AS400 and we have a problem here with a sql-procedure, that is
running OK over the Client Access Navigator, but over the 5250 emulator
hanging with an error "pointer for the given position not set" (anything
like that I think, I have the error in german and here I mean, I have just
translated it, but not sure, if the error is shown in english in that way!).

Here a peace of code:

1 #include <stdlib.h>
2 #include <stdio.h>
3 #include <string.h>
4 #include <decimal.h>
5 #include <wcstr.h>
6 #include <stddef.h>
7 #include <sqlproc.h>
8 typedef _Packed struct GETDIAG_RTN_t {
9 long message_length;
10 long message_octet_l ength;
11 char message_text[1025]; };
............... ............... .... and so on

As I said, running this over the Navigator, works probably well. If I run it
on the 5250 emulator, than I become the error ("pointer for the given
position von set. Application error. MCH3601 .... on 0000000011, instruction
X'0000' not audited").

I think that with the code traslation is sth. wrong. Can you tell me, how
can I use the function "iconv.h" to traslate the code to 1025?
I've searched the KB of IBM Developer and found there a sample, but I have
some problems to use this on our code.

Help will be appreciated. Thanks a lot in advance for your help.

Regard from Germany
Beni

Normally MCH3601 occurs when a program attempts to use a pointer that is
not set. Try recreating the error, and view the job log of the 5250
emulator job. If you have a printed job log, find the "To program" for
the MCH3601 message (exception). If the job is still active, view its
job log using (for example) WRKJOB option 10, place the cursor on the
message and press F1 (Help) followed by F9 (Display message details).
This will also show the "To program" information. This information may
be useful to determine if your program is causing the exception. If it
is, you may be able to use a debugger to determine why the pointer is
not set.

Re usage of iconv(), here is an example found by searching the InfoCenter:
