How to write read dataset statement in unicode

Hi All,
I am writing the program using open dataset concept .
i am using follwing code.
 PERFORM FILE_OPEN_INPUT USING P_P_IFIL.
 READ DATASET P_P_IFIL INTO V_WA.
 IF SY-SUBRC <> 0.
 V_ABORT = C_X.
 WRITE: / TEXT-108.
 PERFORM CLOSE_FILE USING P_P_IFIL.
 ELSE.
 V_HEADER_CT = V_HEADER_CT + 1.
 ENDIF.
Read dataset will work for normal code.
when it comes to unicode it is going to dump.
Please can u tell the solution how to write read dataset in unicode.
Very urget.
Regards
Venu

Hi Venu,
This example deals with the opening and closing of files.
Before Unicode conversion
data:
begin of STRUC,
    F1 type c,
    F2 type p,
end of STRUC,
DSN(30) type c value 'TEMPFILE'.
STRUC-F1 = 'X'.
STRUC-F2 = 42.
Write data to file
open dataset DSN in text mode. ß Unicode error
transfer STRUC to DSN.
close dataset DSN.
Read data from file
clear STRUC.
open dataset DSN in text mode. ß Unicode error
read dataset DSN into STRUC.
close dataset DSN.
write: / STRUC-F1, STRUC-F2.
This example program cannot be executed in Unicode for two reasons. Firstly, in Unicode programs, the file format must be specified more precisely for OPEN DATASET and, secondly, only purely character-type structures can still be written to text files.
Depending on whether the old file format still has to be read or whether it is possible to store the data in a new format, there are various possible conversion variants, two of which are introduced here.
After Unicode conversion
Case 1: New textual storage in UTF-8 format
data:
begin of STRUC2,
    F1 type c,
    F2(20) type c,
end of STRUC2.
Put data into text format
move-corresponding STRUC to STRUC2.
Write data to file
open dataset DSN in text mode for output encoding utf-8.
transfer STRUC2 to DSN.
close dataset DSN.
Read data from file
clear STRUC.
open dataset DSN in text mode for input encoding utf-8.
read dataset DSN into STRUC2.
close dataset DSN.
move-corresponding STRUC2 to STRUC.
write: / STRUC-F1, STRUC-F2.
The textual storage in UTF-8 format ensures that the created files are platform-independent.
After Unicode conversion
Case 2: Old non-Unicode format must be retained
Write data to file
open dataset DSN in legacy text mode for output.
transfer STRUC to DSN.
close dataset DSN.
read from file
clear STRUC.
open dataset DSN in legacy text mode for input.
read dataset DSN into STRUC.
close dataset DSN.
write: / STRUC-F1, STRUC-F2.
Using the LEGACY TEXT MODE ensures that the data is stored and read in the old non-Unicode format. In this mode, it is also possible to read or write non-character-type structures. However, be aware that data loss and conversion errors can occur in Unicode systems if there are characters in the structure that cannot be represented in the non-Unicode codepage.
Reward pts if found usefull :)

Bind variables are of the form $1, $2, etc., so your query stmt should look like:
select * from INFOCOLUMN WHERE employee_id=$1

How to write a search statement under region source?

I want to write a search statement under region source, how to do that? I want it work exactly like this:
Select firstname || lastname as name from employee
where searchstring like '%firstname%' or searchstring like '%lastname%'
Thanks.

Hello,
You can define two text items on your report region – Px_FIRSTNAME and Px_LASTNAME. You should condition the report by these items not being null. You’ll also need a submit button. In the first page load, the report will not be rendered, as the search items are null. After submit, their values will be set on session state, and your report will be able to use them.
In the report query, you are using the page items as if they are bind variables. In your example, you can use something like this:
Select firstname ||' '||lastname as name
from employee
where firstname like '%'||:Px_FIRSTNAME||'%'
or lastname like '%'||:Px_LASTNAME||'%'You can, of course, use any where clause you need to get the desired results.

Arie.

How to Write\Read NI-9516 module in FPGA Project?

Hi,
I use NI-9149 RIO and NI-9516 module.
I want to write to the 9516 throw the FPGA.
My project look like this:
How can I do It?
Thanks for advance,
Aviad
P.S: I read this paper, but don't know how to work throw it...

Hi aviadCielo,
I would use the cRIO in hybrid mode. We have a helpful KB on using 951x modules in hybrid mode (http://digital.ni.com/public.nsf/allkb/12287236ED86B789862576630059572C). From there you can create a virtual axis and program in SoftMotion. This will save you from having to do FPGA programming with the 9516.
Let me know if this works or if you still have the issue.

How to Write/Read to files from Forms 6.0

I would like to write some data to a file from Developer 2000.

Dear Vinayak prabhu,
I cannot make use of the stored procedure (using the util_package) or the Text_io package (from forms). This is because, only normal operations (like put_line,get_line...)are possible using the above procedure calls.
Since I would like to change the "size" and "font" of the text written to the file, i would be requiring a procedure (package) wherein the above properties can be set for each line or para or page ..etc.
Can you suggest me a suitable solution ?
Ramnath Balasubramanian
<BLOCKQUOTE>quote:<HR>Originally posted by vinayak prabhu ([email protected]):
Hi Ramnath
In forms you can use text_io package to read or write to a ASCII file or else write a stored procedure and use util_file which also does the reading and writing to a ASCII file.This stored procedure can be called from a form.

How to write a perform in Sap Script

Hi Guys,
Can anyone let me know how to write a perform statement in Sap Script.
Thanks,
Ramesh

I just took this example from SAP Help
=======================================
Syntax in a form window:
/: PERFORM <form> IN PROGRAM <prog>
/: USING &INVAR1&
/: USING &INVAR2&
/: CHANGING &OUTVAR1&
/: CHANGING &OUTVAR2&
/: ENDPERFORM
INVAR1 and INVAR2 are variable symbols and may be of any of the four SAPscript symbol types.
OUTVAR1 and OUTVAR2 are local text symbols and must therefore be character strings.
The ABAP subroutine called via the command line stated above must be defined in the ABAP report prog as follows:
FORM <form> TABLES IN_TAB STRUCTURE ITCSY
OUT_TAB STRUCTURE ITCSY.
ENDFORM.

Read dataset - read data randomly

Dear All,
I am facing a strange problem while reading data through READ DATASET statement.
The data is getting read randomly from the file.
For example, if my text file contains 10,000 records, i am able to see around 800 in my internal table.
Also, with read dataset statement, sometimes first record gets read, second time fifth record and so on. There is no particular order.
Read dataset statement is skipping a lot of records while reading data from the file.
Has anyone face this problem earlier?
Any clue in this direction will be highly appreciated.
Many thanks.
Best Regards,
Tarun

Hi,
how you are looking your input file, if it is in NOTEPAD check menu option 'Format----> Word wrap' is unchecked and then see the how many entries are there in the file.

How to save/load player stats?

Okay..this should be my last for a while. The last thing I need to know is how to be able to save/load player stats. I'm working on an RPG and need to know how to create a save file with the players hp, mp, lvl, weapons, and so on, and then be able to load it back later on in the game. Any help would be greatly appreciated.

Okay, if this helps any, in one of my JFrames, It
displays the following:JFrames have nothing to do with it. Try to separate your GUI from your data and "business logic," both in your mind and in your code. The data and logic are what they are, whether there's a GUI or not. The GUI just displays the data, takes input from the user, and kicks off this or that bit of the logic.
name, lvl, hp, mp, def, att, exp all stored as 'int's
with the exception being name since it's a string. You should define a class (Player or Character might be a good name) that encapsulates that data. That class should be Serializable, or you should use the XMLEncoder/Decoder. Either way, you can just write an instance of that class to a stream, and then later read it back from a stream. I guess you want that stream to go to a file, but that's independent of how you write/read it.
I
need those variables saved to a file (name doesn't
matter to me), then reloaded the next time the player
starts the game. I want to be able to have multiple
save files. Does the user pick the file name? What do you mean "multiple save files"? One for each user? Or any given user able to save multiple different games in progress?
In any case, saving and reloading many files is no different than one file. Either way you need a way to know or select the file name. But all the work you do is the same.
I guess this sounds a little hard, butNo, not at all. Just slightly unclear on certain details of the requirements and on what part in particular is hanging you up.
