Using a symbol in an operation

Hello,
Here is my problem:
I have to do this operation for example: 2 * 3
I have:
int a=2;
int b=3;
char c= *;
What is the command to make 2*3 with a,b,c in Java 5.0?
Thank you very much!!

There is no built in dynamic expression evaluation, so either you have to do it, or you have to get a 3rdparty library to do it.
There a gizillion such projects, here is one of them for instance: http://sourceforge.net/projects/expression4j/
(not that i'm particularly recommending it over anything else).

Hi,
I had similar requirement wherein I was supposed to display different data using 2 different internal tables on a subscreen area.
The screen consists of two parts: 1) selection-screen with few input fields and two buttons 2) Subscreen area where the report need to be displayed. This report is displayed based on the button that the user is selecting. For this I have done the following things:
1. Capture the sy-ucomm when user is clicking on any of the two buttons in PAI. Then perform data fetch operation.
         MODULE USER_COMMAND_9003 INPUT.
             CASE OK_CODE.
                 WHEN 'DETAIL'.
                   GV_RPT = OK_CODE.
                   PERFORM F_GET_DETAIL_DATA.
                 WHEN 'REPORT'.
                   GV_RPT = OK_CODE.
                   PERFORM F_GET_REPT_DATA.
               ENDCASE.
         ENDMODULE.                 " USER_COMMAND_9003 INPUT
2. Declare two different ALV's with the fieldcat similar to 2 internal tables respectively. Use the above sy-ucomm PBO to call appropriate ALV.
         MODULE DISPLAY_ALV OUTPUT.
           IF GV_RPT EQ 'DETAIL'.
             PERFORM F_FIELDCAT_DETAIL.
             PERFORM F_LAYOUT_DETAIL.
             PERFORM F_EXCLUDE_TOOLBAR_DETAIL.

             PERFORM F_LAYOUT_REPT.
             PERFORM F_EXCLUDE_TOOLBAR_REPT.

How to use field symbols

can anyone tell me how to use field symbols. What effect it has on performance of a program?
what r its avantages?
iam working on a report where iam facing a lot of problems in performance issue. can anyone tell how field symbols are useful in this regard?
thanx to all

FIELD-SYMBOLS
Basic form
FIELD-SYMBOLS <fs>.
Additions
1. ... STRUCTURE s DEFAULT wa
2. ... TYPE t
3. ... TYPE LINE OF t
4. ... LIKE s
5. ... LIKE LINE OF s
Effect
This statement declares a symbolic field called <fs>. At runtime, you can assign a concrete field to the field symbol using ASSIGN . All operations performed with the field symbol then directly affect the field assigned to it.
You can only use one of the additions.
Example
Output aircraft type from the table SFLIGHT using a field symbol:
FIELD-SYMBOLS <PT>.
TABLES SFLIGHT.
ASSIGN SFLIGHT-PLANETYPE TO <PT>.
WRITE <PT>.
Addition 1
... STRUCTURE s DEFAULT wa
Effect
Assigns any (internal) field string or structure to the field symbol from the ABAP/4 Dictionary ( s ). All fields of the structure can be addressed by name: <fs>-fieldname . The structured field symbol points initially to the work area wa specified after DEFAULT .
The work area wa must be at least as long as the structure s . If s contains fields of the type I or F, wa should have the structure s or at least begin in that way, since otherwise alignment problems may occur.
Example
Address components of the flight bookings table SBOOK using a field symbol:
DATA SBOOK_WA LIKE SBOOK.
FIELD-SYMBOLS <SB> STRUCTURE SBOOK
DEFAULT SBOOK_WA.
WRITE: <SB>-BOOKID, <SB>-FLDATE.
Addition 2
... TYPE t
Addition 3
... TYPE LINE OF t
Addition 4
... LIKE s
Addition 5
... LIKE LINE OF s
Effect
You can use additions 2 to 5 to type field symbols in the same way as FORM parameters (see also Type assignment of subroutine parameters). ASSIGN performs the same type checks as with USING parameters of FORM s.

How to use field symbol in select

Hi,
    CONCATENATE 'WTG0' LV_MON INTO LV_FNAME.
    ASSIGN (LV_FNAME) TO <FS>.
    SELECT SINGLE <FS> FROM COSP INTO LV_SAPRST
         WHERE OBJNR = LV_OBJ AND GJAHR = LV_YEAR AND WRTTP = '4' AND KSTAR = GT_INOUT-SAKNR
   Error message :    Unknown column name "<FS>" . field list. . field list. field list.
   actually , if i use if command, i can do, but i want to use simple code by fieldsymbol.
   is it possible in select command?
Thanks in advance

Hi

Field Symbols
Field symbols are placeholders or symbolic names for other fields. They do not physically reserve space for a field, but point to its contents. A field symbol cam point to any data object. The data object to which a field symbol points is assigned to it after it has been declared in the program.
Whenever you address a field symbol in a program, you are addressing the field that is assigned to the field symbol. After successful assignment, there is no difference in ABAP whether you reference the field symbol or the field itself. You must assign a field to each field symbol before you can address the latter in programs.
Field symbols are similar to dereferenced pointers in C (that is, pointers to which the content operator * is applied). However, the only real equivalent of pointers in ABAP, that is, variables that contain a memory address (reference) and that can be used without the contents operator, are reference variables in ABAP Objects.
All operations programmed with field symbols are applied to the field assigned to it. For example, a MOVE statement between two field symbols moves the contents of the field assigned to the first field symbol to the field assigned to the second field symbol. The field symbols themselves point to the same fields after the MOVE statement as they did before.
You can create field symbols either without or with type specifications. If you do not specify a type, the field symbol inherits all of the technical attributes of the field assigned to it. If you do specify a type, the system checks the compatibility of the field symbol and the field you are assigning to it during the ASSIGN statement.
Field symbols provide greater flexibility when you address data objects:
If you want to process sections of fields, you can specify the offset and length of the field dynamically.
You can assign one field symbol to another, which allows you to address parts of fields.
Assignments to field symbols may extend beyond field boundaries. This allows you to address regular sequences of fields in memory efficiently.
You can also force a field symbol to take different technical attributes from those of the field assigned to it.
The flexibility of field symbols provides elegant solutions to certain problems. On the other hand, it does mean that errors can easily occur. Since fields are not assigned to field symbols until runtime, the effectiveness of syntax and security checks is very limited for operations involving field symbols. This can lead to runtime errors or incorrect data assignments.
While runtime errors indicate an obvious problem, incorrect data assignments are dangerous because they can be very difficult to detect. For this reason, you should only use field symbols if you cannot achieve the same result using other ABAP statements.
For example, you may want to process part of a string where the offset and length depend on the contents of the field. You could use field symbols in this case. However, since the MOVE statement also supports variable offset and length specifications, you should use it instead. The MOVE statement (with your own auxiliary variables if required) is much safer than using field symbols, since it cannot address memory beyond the boundary of a field. However, field symbols may improve performance in some cases.

Can I use Unix symbolic links between Mountain Lion and Snow Leopard Mail folders?

After upgrading to Mountain Lion, I partitioned my iMac HD to have two partitions: Macintosh HD has Mountain Lion; I reinstalled Snow Leopard on Macintosh HD 2. Best part: you can access your user-created files from EITHER disk partition. But not so OS X Mail. I wanted to revert to Snow Leopard, since I don't like the iOS-like Mountain Lion (swipe THIS!), but Mail is a problem since all my Snow Leopard Mail was successfully migrated over to Mountain Lion during upgrade.
Is there a way to use Unix symbolic links between actual OS X Mail folders in Mountain Lion and OS X Mail in Snow Leopard?
It seems the (trial) symbolic link created pointed to a blank file.

It's not a matter of "letting" each maintain its own database, William. By default, I believe, I have no control over what gets written. In fact, if there were a way to set a preference that says, use this index named "spotlightindexSL' only [while in SL], that might solve my problem. Then when booting up in ML, it would just go after the index it last made.
My guess is that while I am in ML or SL and not the other, there are all sorts of changes to files and the system freaks and says "Oh, now look at what a mess I've made — there are all sorts of files unaccounted for. Now I have to rebuild the whole thing."
I have 2 had drives in my Mac, both 500GB. One (Working Disk) has no operating system and all my files, and the other drive is partitioned 470/30gb with SL on the 470 and ML in the 30. When I restart in either OS, the auto-start Indexing as if for the very first time, and do both hard drives (in total: 3 partitions of files, not counting the ML Restore partition).
I know it all uncoventionally — just wanted to see what my $20 new OS will cost me in software upgrades, in particular my $1800 Adobe Design Suite CS4 and a few others.

Can I move the common library or use a symbolic link so that Dropbox can sync it?

A team of us are now using Fireworks for interaction design, and need to synchronise the common library so that the elements we use are up to date.
1. Is the common library the correct method?
2. we use dropbox, and I don't think I can tell dropbox to synchronise just the common library folder (as an isolated path from the rest of the dropbox tree...) - so, is there a trick using a symbolic link we could use so that dropbox thinks the common library is actually in it's own tree? (OSX is BSD afterall...)
We're on Mac OSX 10.7.X, running FW CS6 and using the latest dropbox for Mac.
I look forward to hearing some ideas. The question of teams using fireworks has been raised several times since 2009, and Adobe still hasn't got a solution. The mind boggles as to whether or not Adobe takes Fireworks seriously - I hope they do...
All the best,
Dylan

Thanks groove25.
I did find that it is possible to use symbolic links and Dropbox to synchronise the common library across computers. It does come with its idiosynchrasies though (excuse thepun).
I'm going to have a go with what this thread recommends:
http://hints.macworld.com/article.php?story=20120803093247391
and leichter's explanation and walkthrough (nested in the thread) looks very helpful:
There's a subtle point that, once you understand it, makes symlinks much more useful in Dropbox.
The whole design of symlinks in Unix tries to make them invisible to programs that don't specifically try to manipulate them. So suppose 'sym' is a symlink to 'file'. If a program opens 'sym' for read, it actually gets the data in 'file'. If it appends to 'sym', it actually appends to 'file'. However, if it deletes 'sym', what disappears is the link 'sym', not the file 'file'. Opening 'sym' for writing as a new file - not appending to it - is equivalent to deleting the old file and creating a new one: It leaves 'file' unchanged and creates an entirely new file named 'sym' which no longer has any connection with 'file'.
A link to a directory follows the same rules. Looking a file up using the symlink as the name really searches the linked-to directory. Creating a file through the symlink is like appending: It creates the entry in the linked directory. And so on.
A program that wishes to do something special - like change where a symlink points - has to be aware that it's dealing with a symlink and use special OS calls for that exact purpose.
Dropbox works with symlinks *but it doesn't do anything special with them*. So suppose you put that 'sym' linked to 'file' in your Dropbox directory. Dropbox comes along, finds a new file, and sends it to its servers. What does it send? Well, first the name 'sym', and then the "contents" - i.e., what it gets from reading 'sym' which is exactly the contents of 'file'. On the server, and then later on other clients, what you will find is a normal file named 'sym' with the contents of 'file'. *There is no connection with a file named 'file'.* If you change 'file' on the system where 'sym' links to it, the changes propagate. If you change it anywhere else, the changes propagate back - but Dropbox doesn't modify files in place, it writes entire new ones. So the effect back on the original system is to break the link and write a new file named 'sym' with the latest contents - but no connection to 'file'.
I know of no way to keep a link to a *file* as a symlink across updates. But the story is different for *directories*. Unlike ordinary files, directories are normally updated in place (unless you explicit delete and recreate them). So you can do the following:
1. Create directory 'dir' anywhere you like.
2. Create symlink 'dirlink' pointing to 'dir' in your Dropbox folder.
3. Wait for 'dirlink' to appear on all other clients. It will appear as an ordinary directory, not as a symlink. If the original 'dir' had files in it, those will now appear as files on the clients, too.
4. On each client, rename 'dirlink' to 'dir' *in the place you want it to appear in your directory tree*. (Renaming only works if you are staying not the same device. Otherwise, you need to create 'dir' and move all the files.) This need not be the same on all clients, though it's easier to keep track of if it is.
5. On each client, create symlink 'dirlink' pointing to 'dir'.
Now you have a 'dirlink' on each client, which will to Dropbox look like a subdirectory - and it will sync all the files in that "subdirectory". Changes made on any client to any file in 'dir' aka 'dirlink' will be synced to all the other clients as well. Files created or deleted in 'dir' will be created/deleted on every other client as well.
It's probably easiest to do all this while there are no files in 'dir'. Otherwise, Dropbox sometimes repeatedly syncs the same files until everything eventually settles down.
The limitations here:
- Some platforms (e.g., iOS) don't support symlinks. To them, 'dirlink' will just be an ordinary subdirectory.
- Any time you add a new client, you have to go through the process for that client. Certain reset operations in Dropbox - anything that requires re-syncing every file in the Dropbox folder on a client - will require the same, because Dropbox doesn't know how to *create* symlinks - it'll just create an ordinary subdirectories.
I've used this configuration for a couple of years. You have to watch out for the reset situations and such, but generally once you have it set up, it "just works".

Hi, I am having a little trouble with exporting images to another drive and Catalogue and need some help if anyone can give me some advice
I am currently using Lightroom 5.6 and operating on a Mac with OSX Ver 10.9.5.
I am receiving an error problem when doing the following -
I am exporting selected photos from a particular Catalogue saved on Drive 1 to a folder created on another Drive where a Lightroom Catalogue has been created. In this Catalogue I have arranged for the images once exported to be moved to a different folder - I used the Auto Import process under the File dialogue box.
When processing the Export I receive an error message for each of the images being exported indicating the following -
Heading Import Results
Some import operations were not performed
Could not move a file to requested location. (1)
then a description of the image with file name
Box Save As Box OK
If I click the OK button to each image I can then go to the other Catalogue and all images are then transferred to the file as required.
To click the OK button each time is time consuming, possibly I have missed an action or maybe you can advise an alternative method to save the time in actioning this process.
Thanks if you can can help out.

Thank You, but this is a gong show. Why is something that is so important to us all so very, very difficult to do?

How can I use Greek symbols in a text in Pages? Greek symbols are not in the special character list.

How can I use Greek symbols in a Pages text? Greek symbols are not included in the special character collection.
I need to import for example a sigma from Word or Adobe illustrator and then Pages can recognise it. I can not find it from within Pages.

Special character palette from the edit menu does have sigmas under European ... > Greek ...
You can do a search at the bottom of the Special Character palette. Double click on the greek capital letter sigma. You will get a lot of sigmas.

How to populate one internal table from another using field symbols

Hi Gurus,
I have a problem. I have to populate one internal table (sructure t_otput) from another internal table (sructure t_from) using field symbol.
Structure for from table.
types: begin of t_from,
         year(4) type c,
         ww(2) type c,
         site type marc-werks,
         demand type i,
       end of t_from.
Structure for output table.
types: begin of t_display,
         title(30),
         WW1(10),
         WW2(10),
         WW3(10),
       end of t_display.
The from table looks like this:
Year | WW | Site | Demand
2005 | 1 | OR1 | 12.00
2005 | 2 | OR1 | 13.00
2005 | 3 | OR1 | 14.00
The display table which has to be populated should look like this:
Title | WW1   | WW2   | WW3
OR1    |       |       |
Demand | 12.00 | 13.00 | 14.00
How to populate display table using field symbol?
Please give code snippets
Thanks,
Gopal

Gopal,
Here is the code, however I am not vary clear about the ORG1 and Demand display that you have shown in the display. I am sure with this code it should not be a big deal to tweak in whatever manner you want.
TABLES : marc.
TYPES: BEGIN OF type_display,
title(30),
ww1(10),
ww2(10),
ww3(10),
END OF type_display.
TYPES: BEGIN OF type_from,
year(4) TYPE c,
ww(2) TYPE c,
site TYPE marc-werks,
demand TYPE i,
END OF type_from.
data : t_from type table of type_from,
       t_display type table of type_display.
field-symbols : <fs_from> type type_from,
                <fs_display> type type_display.
data : wa_from type type_From,
       wa_display type type_display.
wa_from-year = '2005'.
wa_from-ww   = '1'.
wa_from-site = 'OR1'.
wa_from-demand = '12.00'.
insert wa_from into table t_from.
wa_from-year = '2005'.
wa_from-ww   = '2'.
wa_from-site = 'OR1'.
wa_from-demand = '13.00'.
insert wa_from into table t_from.
wa_from-year = '2005'.
wa_from-ww   = '3'.
wa_from-site = 'OR1'.
wa_from-demand = '14.00'.
insert wa_from into table t_from.
data : variable(3) type c.
field-symbols : <fs_any> type any.
break-point.
Loop at t_from assigning <fs_from>.
variable = 'WW'.
wa_display-title = <fs_from>-site.
concatenate variable <fs_from>-ww into variable.
assign component variable of structure wa_display to <fs_any>.
<fs_any> = <fs_from>-demand.
endloop.
append wa_display to t_display.
clear wa_display.
loop at t_display assigning <Fs_display>.
write :/ <fs_display>.
endloop.
Note : Please award points if this helps you.

Using Text Symbols In Webdynpro

Hi Experts,
   When i created a text symbol in my assistance class and provided it to my attribute via the set attribute method it is not working. Is there a different way of using Text Symbols or Text Elements
compared to normal ABAP Programming.
Thanks In Advance,
Chaitanya.

Thanks For Your Reply,
CALL METHOD l_if_el_node_header->set_attribute
    EXPORTING
     value =   TEXT-001
     name   = 'INPUT_STATE'.
where 001 is the text symbol 'Sym' which has been assigned to the text " DISPLAY MODE " in my
assistance class.
i am guessing we need not preceed 001 with TEXT in the above code , please reply with your inputs.
With Regards,
Chaitanya.

Delete row from internal table using field symbol.

Hi friends,
I created dynamic internal table using field symbol. I want to delete some data using where clause.
for example. i want to use like,
DELETE <FS> WHERE KUNNR = WA_KNA1-KUNNR.
Like the above statment it won't work. How i can use delete with where clause in field symbols.
Hope any one can help me.
Thanks and regards
Srikanth. S

hi Srikanth,
I think you have to LOOP through the whole internal table and check each line and decide to delete or not:
LOOP at <itab> INTO <wa>.
ASSIGN COMPONENT 'KUNNR' OF STRUCTURE <wa> TO <field>.
CHECK <field> IS ASSIGNED.
IF <field> EQ WA_KNA1-KUNNR.
DELETE ...
ENDIF.
UNASSIGN <field>.
ENDLOOP.
hope this helps
