How to use math symbols in Pages

How can I find math symbols in Pages?
Do I need additional Software or is there a possibility as in Microsoft Word?

You can find some math symbols in Pages if you go to Special Characters. Open Pages, go to Edit menu (on the menu bar) > Special Characters, and choose math symbols in the sidebar, so you will be able to add a symbol double-clicking the symbol.
However, it may not include all symbols. In this case, you will have to use other third-party applications

How to use math symbols in a right to left text properly?

Hey there
When I write a simple mathematical equation or a number(which has sign) in the middle of a right to left text in a text box(I simply set keyboard language to EN for typing expressions & numbers) it's like mathematical symbols are somehow not considered math symbols and that's weird since in word it's not that way, take the following sentence for example that means result of the 0-127 expression is -127:
حاصل عبارت 127-0 برابر 127- است.
In word I can type it just fine(for typing expressions and numbers I set keyboard language to EN) but when I type it the same way in adobe acrobat I get this:
حاصل عبارت 0-127 برابر -127 است.
copy & paste from word also doesn't do any help, so If I want to get it right I should type math expressions from right to left meaning as instance to type 0-127 I should first type 127 then - and finally 0 also should type digits of a number before typing its sign as example for typing -127 I should first type 127 then - ,now I wonder is it the way acrobat works or I'm doing something wrong.
By the way OMG o_O even when I did copy & paste my messasge from word to the text box of forum for posting, it ended up treating math parts in upper right to left paragraph the same way as acrobat I just had to write them from right to left!
Anyone has any idea?
Message was edited by: Pooria

In a word document I wrote:
حاصل عبارت 127-0 برابر 127- اسـت
Then tried printing it using "Adobe PDF" printer, in output pdf that sentence was written in right order and interestingly it was broken into three text boxes thanks for reply.

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 symbols in program

how to use field symbols can any one explain with example please..

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.

How to use Field-symbol with dynamic select query

Can anybody tell me, how to use field-symbols in the dynamic select query.

FIELD-SYMBOLS <fs> { typing | STRUCTURE struc DEFAULT dobj }.
1. ... typing
2. ... STRUCTURE struc DEFAULT dobj
The FIELD-SYMBOLS statement declares a field symbol <fs>. The name conventions apply to the name fs. The angle brackets of the field symbols indicate the difference to data objects and are obligatory. You can declare field symbols in any procedure and in the global declaration section of an ABAP program, but not in the declaration section of a class or an interface. You can use a field symbol in any operand position in which it is visible and which match the typing defined using typing.
After its declaration, a field symbol is initial - that is, it does not reference a memory area. You have to assign a memory area to it (normally using the ASSIGN statement) before you can use it as an operand. Otherwise an exception will be triggered.
eg.
FIELD-SYMBOLS <fs> TYPE ANY.
DATA: BEGIN OF line,
        string1(10) VALUE '0123456789',
        string2(10) VALUE 'abcdefghij',
      END OF line.
WRITE / line-string1+5.
ASSIGN line-string1+5(*) TO <fs>.
WRITE / <fs>.
output:

How to use URL CHIPs in Page Builder?

Hi all,
I have encountered a problem of using URL CHIPs in CHIP Catalog.
I cannot find any documents on how to use the CHIPs in CHIPs Catalog of Page Builder. I just simply want to display a URL in NWBC. I suppose that there is an input in URL CHIPs for URL addresses and then the URL can display. However, it is not the case.
I have already looked at the template of URL CHIPs (WDR_TEST_PAGE_CHIP_PROV_2) and still I don't understand how to use the URL CHIP.
Please give me some hints on this one.

How to use Keynote tuxtures in Pages

Hi All,
In keynote graphs you have different textures than in Pages. Does anyone know how to use the Keynotes textures in Pages?
Doest anyone know if I can download more textures for iWork on the Web?

The three components of iWork '09 (as the iWork '08 ones) share the same folder of textures.
So, If Pages doesn't use all of them, it's a design choice.
If I made no error, here is a table of used textures.
Some are news and unused ?
I found no change in the use of textures for Pages and Numbers.
The changes apply only to Keynote.
I entered the program's resources and bingo, I found the way to allow more textures in the menus.
<startupVolume>:Applications:iWork '09:Keynote.app:Contents:Resources:SFCChartFills.plist
<startupVolume>:Applications:iWork '09:Numbers.app:Contents:Resources:SFCChartFills.plist

How to use math formula on waveforms

Hi all,
I'm trying to create a program that can use math scipts, formulas etc on waveforms. I've done it for one signal, but I don't know how to change work on 2 or more signals;/ Let's see exampe: one channel is voltage, the second is current and I want to see both of them and as a third signal power so I'm writting formula ch3=ch1*ch2. Another example: I've signal which represents speed of starting motor (500 points) but I need only few points so the formula will be: ch1(20:120) and I have points from 20 to 120. Is it possible to do it? I can't do it using blocks cause I don't know which signal means what... so ch1 can be voltage, ch2 speed, ch3 current ch4-torqu etc. I know that I can cut a part of signal by subarray or subwaveform but it must be done by formula to use (for example) something like that:
ch1(1:20)=0 <- replace all point from 1 to 20 of ch1 by 0
ch2(50)=40 <-replace point 50 of ch2 by 40
ch3=ch1*2 + ch2 <- do this operation but first do both above this one.
Is it possible? or it's to complicated?
I attached my vi which is working for one selected signal (I don't want to select it... but I don't know how to do it;/) and signal that I'm using to check how it's work
Thanks
Mike

Archive.zip ‏134 KB
math formula.vi ‏152 KB

I've upgraded it a little and it works with 2 signals but very sensible;/ formula must have this construction: c3= ... , both of signals must be switched on, there's no way to use part of signal (e.g.c1(21:54) ) and I can't use 2 rows (something like this: c3=c1*c2; c3=c1 doesn't work);/ additionally I wanted to have possibility to use all of signals as input and all of them as output

How to use field-symbols in MODIFY ... TRANSPORTING and SORT

Hi,
I need to increase the performance of an abap report using the field-symbols. More exactly the code is the following.
TYPES:
BEGIN OF itab_structure.
     INCLUDE STRUCTURE nameofstructure.
TYPES:
     RECNO   LIKE sy-tabix,
END OF itab_structure.
DATA:
itab TYPE STANDARD TABLE OF itab_structure
       WITH HEADER LINE
       WITH NON-UNIQUE DEFAULT KEY INITIAL SIZE 0.
SORT itab ASCENDING BY f1.
LOOP AT itab WHERE f1 = '10'.
    itab-fn= value-n.
MODIFY itab
             TRANSPORTING fx fy fz ft
                    WHERE f1   = c1_filed AND
                                  f2   = c2_field.
ENDLOOP.
I need your suggestions in this kind of conversion or solution.
SORT itab ASCENDING BY f1 (<-- I don't know if in this case the better performances should be obtained using field symbols and in which way)
FIELD-SYMBOLS: <fs_itab_line> TYPE LINE OF itab.
LOOP AT itab ASSIGNING <fs_itab_line> WHERE
<fs_itab_line>-f1 = '10'.
MODIFY itab
             TRANSPORTING fx fy fz ft
                    WHERE f1   = c1_filed AND
                                  f2   = c2_field.
(I don't know if in this case the better performances should be obtained using field symbols and in which way)
ENDLOOP.
I wish to implement the field symbols or the better performance in terms of execution time in all my abap code, where it is possible.
Any suggestion will be well appreciated.
Thanks in advance for your kind support.
Regards,
       Giovanni

Dear All,
I have appeciated your suggestions and I can conclude these points in my case:
1) The "sort" statement is not optimized in a different way using filed-symbols
2) The loop with "where" condition on a standard table is performed using filed-symbols
But ... my last point to investigate is about the statement MODIFY table TRANSPORTING f1, f2 WHERE conditions.
More exactly, in my code the execution logic of the abap code expects a global modification of the same table at the end of every (primary) loop, using the MODYFY statement.
In other words in my code I can locate two loops on the same table in the following logic:
LOOP AT table1 WHERE f1 = '10'. (#1)
      updates to table1
      set c1_filed, c2_filed
      LOOP AT table1.   (#2)
         IF f1 = c1_filed AND
            f2 = c2_filed.
           table1-fx = 'x'.
           table1-fy = 'y'.
           table1-fz = 'z'.
           table1-ft = 't'.
         ENDIF.
         MODIFY table1.
      ENDLOOP.   (#2)
ENDLOOP.   (#1)
In better way (maybe more fast in terms of execution time) to modify a set of lines (MODIFY...TRANSPORTING...WHERE):
LOOP AT table1 WHERE f1 = '10'.
   table1-fx= 'x'.
   table1-fy= 'y'.
   table1-fz= 'z'.
   table1-ft= 't'.
   MODIFY itab
      TRANSPORTING fx fy fz ft
   WHERE f1 = c1_filed AND
         f2 = c2_field.
ENDLOOP.
My aim is to use field-symbols everywhere possible for speeding up the execution of my code,by maintaining this logic.
My proposal should be the following but I need your kind opinion.
FIELD-SYMBOLS: <fs_#1_line> TYPE LINE OF table1.
FIELD-SYMBOLS: <fs_#2_line> TYPE LINE OF table1.
LOOP AT table1 WHERE f1 = '10' ASSIGNING <fs_#1_line>. (#1)
      updates to table1
      set c1_filed, c2_filed
      LOOP AT table1 ASSIGNING <fs_#2_line>. (#2)
         IF <fs_#2_line>-f1 = c1_filed AND
            <fs_#2_line>-f2 = c2_filed.
           <fs_#2_line>-fx = 'x'.
           <fs_#2_line>-fy = 'y'.
           <fs_#2_line>-fz = 'z'.
           <fs_#2_line>-ft = 't'.
         ENDIF.
      ENDLOOP.   (#2)
ENDLOOP.   (#1)
Your kind support is very important for me.
Thanks in advance.
