Calling fortran subroutine from C in sunstudio

I am using Sun Studio 12 under Linux,
Could anyone give me an example project which shows how to use a fortran subroutine in C.
For example in the project "application_1" I have 2 source codes one with .c and the other one with .f90 extension. The main source is the C code but this one call a fortran subroutine "mysub". I am going to do it in a project in Sun Studio not via command line.
Thanks.

Refer to Chapter 11 "C-Fortran Interface" in the Fortran Programming Guide:

How to call a subroutine from sap script

hi friends,
Can anybody tell me How to call a subroutine from sap script .
thanks n regards .

hi..
Calling ABAP Subroutines: PERFORM
You can use the PERFORM command to call an ABAP subroutine (form) from any program, subject to the normal ABAP runtime authorization checking. You can use such calls to subroutines for carrying out calculations, for obtaining data from the database that is needed at display or print time, for formatting data, and so on.
PERFORM commands, like all control commands, are executed when a document is formatted for display or printing. Communication between a subroutine that you call and the document is by way of symbols whose values are set in the subroutine.
The system does not execute the PERFORM command within SAPscript replace modules, such as TEXT_SYMBOL_REPLACE or TEXT_INCLUDE_REPLACE. The replace modules can only replace symbol values or resolve include texts, but not interpret SAPscript control commands.
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.
The values of the SAPscript symbols passed with /: USING... are now stored in the internal table IN_TAB . Note that the system passes the values as character string to the subroutine, since the field Feld VALUE in structure ITCSY has the domain TDSYMVALUE (CHAR 80). See the example below on how to access the variables.
The internal table OUT_TAB contains names and values of the CHANGING parameters in the PERFORM statement. These parameters are local text symbols, that is, character fields. See the example below on how to return the variables within the subroutine.
From within a SAPscript form, a subroutine GET_BARCODE in the ABAP program QCJPERFO is called. Then the simple barcode contained there (First page, Next page, Last page) is printed as local variable symbol.
Definition in the SAPscript form:
/: PERFORM GET_BARCODE IN PROGRAM QCJPERFO
/: USING &PAGE&
/: USING &NEXTPAGE&
/: CHANGING &BARCODE&
/: ENDPERFORM
/ &BARCODE&
Coding of the calling ABAP program:
REPORT QCJPERFO.
FORM GET_BARCODE TABLES IN_PAR STUCTURE ITCSY
OUT_PAR STRUCTURE ITCSY.
DATA: PAGNUM LIKE SY-TABIX, "page number
NEXTPAGE LIKE SY-TABIX. "number of next page
READ TABLE IN_PAR WITH KEY PAGE.
CHECK SY-SUBRC = 0.
PAGNUM = IN_PAR-VALUE.
READ TABLE IN_PAR WITH KEY NEXTPAGE.
CHECK SY-SUBRC = 0.
NEXTPAGE = IN_PAR-VALUE.
READ TABLE OUT_PAR WITH KEY BARCODE.
CHECK SY-SUBRC = 0.
IF PAGNUM = 1.
OUT_PAR-VALUE = |. "First page
ELSE.
OUT_PAR-VALUE = ||. "Next page
ENDIF.
IF NEXTPAGE = 0.
OUT_PAR-VALUE+2 = L. "Flag: last page
ENDIF.
MODIFY OUT_PAR INDEX SY-TABIX.
ENDFORM.

Hi ramakrishna,
1. while calling subroutines from sapscripts,
there is a special technique,
which has got its own limitations.
2.
FORM abc
TABLES
in_tab STRUCTURE itcsy
out_tab STRUCTURE itcsy.
ENDFORM.
3. The perform in se38 program should be of the
above format only.
4. We cannot pass internal tables.
5. Rather we need to pass
VARIABLE NAME
VARIABLE VALUE
(see the structure of itcsy in se11)
6. In this form, we have to read
the internal table in_tab
to capture the variable name and its value.
7. Similary, to return the values,
we have to put one record (for each variable)
in out_tab.

amit m.

Calling Fortran from Java

Is it possible to call Fortran code from java??

You can use Runtime.exec() to run an application written in Fortran.
If you can write C/C++ code which interacts with something written in fortran then you can use JNI to connect it to java.
Presumably the fortran app doesn't already have an interface that allows something to interact with it when it runs - like a socket interface.

Calling subroutines from SAPScript

Hi all,
I have added a piece of code in my MAIN window which calls a subroutine in another program. This works just fine. However, when I moved the code from one <b>window element</b> of MAIN to another, the code is no longer triggered.
What causes this to happen? Is it related to the calling of function module WRITE_FORM in the application program? Any ideas?
All helpful answers will be rewarded!

Query regerding Sapscript : Calling abap subroutines

Hello everybody
Hope everyone is doing fine.
I've a small query. Whenever we require to call an abap subroutine from an abap sapscript we do the same using PERFORM statement. The syntax for the same is as below:
PERFORM SUBROUTINE_NAME IN PROGRAM PROGRAM_NAME
USING &VARAIABLE&
CHANGING &VARAIABLE&
ENDPERFORM
Here we are passing the varaiables to the subroutine and getting back values in varaibles. In the actual program we then read values from in_tab and out_tab having structures similar to itcsy.
The above mentioned is as per my understanding. My query is as follows:
If in the above statement instead of passing varaibles abnd getting back variables can be pass/get back an internal table?
I had read somewhere that it is possible using structures. If anyone is aware of how to do the same can you please give me the syntax. Actually how to get value from subroutine into an internal table. What will be the structure? Will it be same as itcsy?
Thanks a lot to everybody in advance.
Thanks & Regards

Calling selection screen from another selecton screen.

Hi guys,
I want to call default selection screen of one program from default selection screen of another program.
Is that possible . would appreciate some helpful answers.
Thanks,
Venkat.

it is possiable.
1.submit
2. call transcation t_code.
Syntax
SUBMIT <prog>.
For more information about the SUBMIT statement, see Calling Executable Programs (Reports)
Assume the following simple report:
REPORT ZDYN3.
WRITE / 'Dynamic Program!'.
The following executable program (report) starts, modifies, and restarts ZDYN3:
REPORT ZMASTER1.
DATA CODE(72) OCCURS 10.
DATA LIN TYPE I.
READ REPORT 'ZDYN3' INTO CODE.
SUBMIT ZDYN3 AND RETURN.
DESCRIBE TABLE CODE LINES LIN.
MODIFY CODE INDEX LIN FROM
'WRITE / ''Dynamic Program Changed!''.'.
INSERT REPORT 'ZDYN3' FROM CODE.
SUBMIT ZDYN3.
The output of this program is displayed on two subsequent output screens. The first screen displays:
Dynamic Program!
The second screen displays:
Dynamic Program Changed !
When you use the SUBMIT statement, all modifications made to a program during runtime take immediate effect before they are submitted. In the above example, ZDYN3 is submitted from ZMASTER1 first in its original and then in its modified form, generating different results.
This is not the case if you change the codes of include programs or subroutines dynamically.
Assume the following include program:
INCLUDE ZINCLUD1.
WRITE / 'Original INCLUDE program!'.
and an executable program (report) for modifying and including it:
REPORT ZMASTER2.
DATA CODE(72) OCCURS 10.
DATA LIN TYPE I.
READ REPORT 'ZINCLUD1' INTO CODE.
DESCRIBE TABLE CODE LINES LIN.
MODIFY CODE INDEX LIN FROM
'WRITE / ''Changed INCLUDE program!''.'.
INSERT REPORT 'ZINCLUD1' FROM CODE.
INCLUDE ZINCLUD1.
If you run ZMASTER2, the source code of include program ZINCLUD1 is changed and replaced in the system. However, the last line of ZMASTER2 executes the older version since the runtime object of ZMASTER2 is generated before ZINCLUD1 is modified. Only when ZMASTER2 is run a second time, does the system determine that ZINCLUD1 has been changed. Exactly the same is true if you dynamically modify the source code of a subroutine and call it from within the same program.
One way to solve this problem is to use the INCLUDE statement within an external subroutine that is called by the program. This allows you to create or modify include programs or subroutines and use the updated versions directly in the same program.
Assume the following include program:
INCLUDE ZINCLUD1.
WRITE / 'Original INCLUDE program!'.
and an external subroutine:
PROGRAM ZFORM1.
FORM SUB1.
INCLUDE ZINCLUD1.
ENDFORM.
The following program reads the include program, modifies it, enters it back into the system, and calls the subroutine.
REPORT ZMASTER3.
DATA CODE(72) OCCURS 10.
READ REPORT 'ZINCLUD1' INTO CODE.
APPEND 'WRITE / ''Extension of INCLUDE program!''.' TO CODE.
INSERT REPORT 'ZINCLUD1' FROM CODE.
PERFORM SUB1(ZFORM1).
This produces the following output:
Original INCLUDE program!
Extension of INCLUDE program!
In this case, the updated version of the include program is used in the subroutine because its time stamp is checked when the subroutine is called, and not when the calling program is generated.

Calling labview VIs from python in Linux

Hello.
I've spent some time searching for this but I haven't found exactly what I was hoping for.
I'm involved in a project that we're starting now and it involves creating a complex software architecture in order to control a robot. This software will need to perform multiple tasks such as interfacing with hardware (which LabView is perfect for) as well as planning and high performance image processing (which LabView isn't as great for).
I was hoping to be able to use a scripting language like python to manage high level stuff (planning, behavior, etc) by calling "subroutines" in other languages such as C++ for the high performance stuff and LabView VIs for the hardware interfacing. I would also like this to run on Linux.
I've found a lot of suggestions on how to call Python scripts from within LabView but this is not what I want. I want exactly the opposite, invoke VIs from Python. I found some information on how to do this on Windows (http://zone.ni.com/devzone/cda/tut/p/id/5719) but this article seems to assume that Windows is being used.
Does anybody have an idea on how to do this?

Unfortunately that's not an option. This is an interdisciplinary school project involving students from engineering (mechanical, electrical and more), computer science and more fields. Some of these students have gotten used to using Labview and this is the main reason I'm trying to accomplish this. I want to have the higher level architecture done in a scripting language such as python which will enable us to create modules in various different environments such as C++ for tasks requiring high performance (image processing for example), Labview for tasks that the people used to using that and even something running on the GPU if there's use for that. Python would make it easy to glue all these components together while maintaining an environment that would make it very easy to configure the whole software system in different ways.
I'd also prefer that this all run on Linux.
The more I look for this the more hopeless I get I'll find anything which is very frustrating. It's a bit hard to believe that Labview doesn't have "python bindings" for running the VIs from within python :-(

Calling compiled subroutines

I would like to programmatically call (load and unload)
subroutines from a VI. There must be a way to do it, but I haven't quite
figured it out.
First the scenario:
ABSTRACT SCENARIO: I have a LabView VI that will end up being compiled into an
EXE. In this VI, I have a file list (Array) of which I will pick one file
each pointing to a VI. I plan on using a Menu Ring that selects one of
the options from the file list and then runs the corresponding VI. I
would like to be able to add or remove VIs
from the list. Furthermore, I would like to be able to change this so
each file in the list points to a compiled function (maybe a dll?).
SPECIFIC SCENARIO: I have a measurement program that controls (adjusts
settings/returns readings) external equipment. I would like to be able to
change the piece of equipment and simply change a measurement subroutine so
that I can "drop in" different modules for each power meter, using
the same main program. I would like to programmatically load and unload
these depending on usage. After compilation of the main program, I would
like to be able to add/change/remove subroutines to accommodate different
equipment.
When I compile the main program, if I compile the supporting VIs, I am no
longer calling VIs. If I don't compile
the supporting VIs, then I am running
uncompiled code from compiled code (not very efficient). I believe the
way to do this is to actively load and unload dlls but I can't seem to do this
programmatically (i.e. define what dll to call based on a file string).
The only dll calls seem to be "Call Library Function Node" and
"Code Interface Node" each which must be linked to a dll a priori.
I thank anyone sincerely for their feedback.

A few points of my own. If, when you say compile, you mean build an ".exe" that is really "building an application", which takes the vi's in your program, essentially builds them into a ".llb" type file, removing diagrams and front panels from all but those that display user interfaces at runtime. When you run the resulting .exe file it is loaded by LabVIEW, the runtime engine version if the development system isn't installed, and I believe compiled at that time. When you run a VI during development, the time delay before running the first time is LabVIEW compiling the code. If you stop the VI and rerun it you will see that it starts running much more quickly the next time.
You can build a structure that dynamically loads called vi's. Depending on the complexity of the called "plugin" there may be a delay before it executes, but it should be pretty brief, partly time to read it from disk, partly to compile the vi's code. I'm pretty sure that subsequent calls to that vi will be essentially instantaneous. Attached is a snip from some of my code that preloads the names and filepathes of vi's that may be run into two arrays and then when a specific vi name is called indexes the filepath based on the name. The VI plugins have to meet the criteria of having identical connector panes in this application, so you would need to develope an architecture that allows that.

Calling a Program from Quomo Feature

From the featuer QUOMO i need to call a cust ABAP Program to make a decison and return the value for QUOMO.
i'm confised that how i would imort the parameters from the efature QUOMO i.e., the personal number and after making the decision how the value of QUOMO could be exported back.
through some other postings i found that the program i'd create should be of type "Subroutine pool".
but i'm still not able to determine how the import and export of variables will take place.

To call a program from feature Quomo you need to add a form named ext_call_f. The form must use the following parameters:
FORM EXT_CALL_F USING NAMEN BACK STATUS PME87 STRUCTURE PME87.
IF PME87-PERNR = '1234'.
BACK = '1'.
ELSE.
IF PME87-PERNR = '4567' .
BACK = '2'.
ENDIF.
ENDIF.

Calling ABAP Subroutines: PERFORM example

hi friends,
Can any one give me an example on Calling ABAP Subroutines: PERFORM or provide any links for that example already posted in sdn ...
points will be awarded
regards and thanks
Vijaya

hi
With the PERFORM statement, you can call subroutines which are coded in the same ABAP program (internal calls), or subroutines which are coded in other ABAP programs (external calls).
You can also specify the name of the subroutine dynamically at runtime, and call subroutines from a list.
Internal Subroutine Calls
To call a subroutine defined in the same program, you need only specify its name in the PERFORM statement:
PERFORM <subr> http://USING ... <pi>...
http://CHANGING... <pi>... .
The internal subroutine can access all of the global data of the calling program.
