Language Systems FORTRAN 2.0

By Jörg Langowski, MacTutor Editorial Board

“Language Systems FORTRAN 2.0”

A new version of the Languages Systems FORTRAN for MPW has just arrived here. Version 2.0 has been improved a lot compared to the previous version - not that version 1.2.1 wasn’t already a very good product. I’d like to give a short overview and some code examples in this month’s column, so that you can appreciate the ease with which Fortran application can now be created on the Mac, or ported from a mainframe to the Mac.

But first of all, a figure that might be very important for many of you Fortran users: the new compiler runs the Whetstone benchmark at 1072 K whetstones/sec (Language Systems FORTRAN 2.0, opt=3, MacIIx) instead of the 425 K whetstones/sec that the version 1 compiler produced. The optimizer now actually works, and depending on the type of the code there can be very significant speed differences from one optimization level to the other. The matrix multiplication benchmark that I described in the V5#8 column, now runs in 2.66 seconds (opt=3, MacIIx) instead of 6.52 seconds (145% faster), if you don’t take the constant index expression out of the loop; or in 2.55 instead of 4.65 seconds (82% faster), if the common subexpression elimination is done by hand on the source code. Thus - at least for these cases - LS Fortran produces code that is now even faster that MPW Pascal’s code, and significantly faster than the same Fortran code on a MicroVAX II.

Built-in Mac interface to FTN programs

The Macintosh interface to Fortran programs has been extensively improved and simplified. It has always been possible to create a typical Macintosh application around a central event loop with mouse down, update and activate handlers etc. entirely in Fortran, and there is a Multifinder-compatible sample Fortran application on the Examples disk. But this is not what the typical Fortran user would have in mind when porting a functioning application from a mainframe to the Mac. Rather, one would like to conserve most of the existing Fortran code and add to it the ease of use of the Macintosh, without having to write a whole new user interface around it.

With the new LS Fortran, such an operation is extremely easy, as long as your program is well-written, i.e., sufficiently modular. There are enough examples of GOTO-clobbered spaghetti code with 25-page long subroutines that I wouldn’t wish my worst enemy having to adapt to a new machine, but as long as you can cut up your code into distinct routines that each fulfil a defined task and then return to a main program, porting the program to the Macintosh becomes child’s play.

To achieve this, Language Systems have expanded on a feature of their system: namely, that a LS Fortran program does not immediately exit to the Finder after the END statement, but returns into a run time system that lets you edit, save or print the output window. The new compiler version allows the user to add new menus and menu items to the menu bar that is drawn after exit from the main program. Each of the menu items can be assigned a pointer to a subroutine that will be executed when the menu is selected. Control returns to the Fortran run time system when the subroutine finishes; there, a new menu selection may be made, either from the default Fortran File, Edit, and Fonts menus, or from any added user menus.

Furthermore, a routine has been added that gives the Fortran program access to the menu items in the Fortran run time menu bar. For instance, to quit to the Finder immediately at the end of a program - instead of keeping the editable output window and the menus available - all you need to do is

CALL DoMenu(‘File’,’Quit’)

at the end of your main program.

The example - a simple graphics display program

Using the new menu features, the Fortran program will be structured in such a way that the main program only does data, window, etc. initialization and sets up the user menus, while the actual work is done by subroutines that are invoked through menu selections. Listing 1 gives an example of such a program, a simple facility to read a file with consecutive lines of x/y coordinate pairs and to plot the corresponding graph in various ways in a graphics window.

Furthermore, one of the subroutines (Listing 2) is written in Pascal and illustrates the possibility of passing parameters either through the procedure’s parameter list or through accessing Fortran’s COMMON data directly.

You’ll notice that two new Fortran compiler directives appear at the beginning of the program. The compiler directive !!G Toolbox.finc is used to load a precompiled ‘global include’ file that contains toolbox variable, structure and parameter definitions. This speeds up recompiling a program considerably if you use lots of toolbox definitions. Global include files can be created to the needs of each individual program, including only those definitions used in the code; or one can simply create one file that contains all the definitions. In the latter case, compiling takes only slightly longer.

Just as the directive !!M Inlines.f was used in version 1.2.1 to make the trap definitions known to the compiler, we can now use !!MP Inlines.f to simplify the calling mechanism. In the latter case, all trap routines are automatically declared as PEXTERNAL, which means that parameter will be passed by value rather than by reference (the Fortran default). This allows you to write

 call SetRect  (%ref(myRect),
 1 int2(20),int2(40),int2(500),int2(235))

rather than

C 1

 call SetRect  (myRect,
 1 %val(int2(20)),%val(int2(40)),
 2 %val(int2(500)),%val(int2(235)))

as you would have to do when call-by-reference is the default. Since toolbox calls receive a great number of their parameters by value, this saves a lot of writing and makes the program much more readable. Of course, the old directive !!M Inlines.f is still available. You may now also declare any other subroutine PEXTERNAL, and further CALLs to that routine will use Pascal calling conventions.

Fortran subroutines may also be declared to receive some of their arguments by value; you write, in the subroutine definition,

C 2

SUBROUTINE XX(A,B,%VAL(I)),

and the routine will expect the value of I on the stack, not its address. This can be important for writing certain filter procedures that are called by toolbox routines.

The Main Program

The main program will first move the Fortran output window to the bottom of the (Mac+) screen, then set up the user menu with its items and their corresponding subroutines. Routines which are not defined in the same source file must of course be declared EXTERNAL (or PEXTERNAL or CEXTERNAL). OutWindowClear, which erases the Fortran output window, is such a case.

After the calls to AddMenuItem, we type a blank line (type *) to have at least one reference to the window output routines in the main program, and thus create the output window. Thereafter, a graphics output window is created.

We must call DoMenu at least once before the main program exits if we want to modify some of the user menu items, for instance set a check mark. Since the menu bar is not created before the main program exits or DoMenu is called, any calls to CheckItem, SetItem, etc. won’t have an effect before.

One line - commented out in the example - calls a routine that was undocumented in the version of the manual that I received (thanks, Claudia Vaughan from Language Systems, for the information!): SetIdleProc receives a pointer to a routine that will be called regularly from the Fortran run time system’s main event loop. Here, that routine would just beep once (that’s why I commented it out in the final version). SetIdleProc could be used to do background calculations or refresh graphics windows, since the present system does not allow to associate update routines with windows, unless the complete event loop is rewritten in Fortran.

File access through the SF dialog

The routine that reads in the data, readData, shows a non-standard extension that LS has made to the Fortran OPEN statement:

C 3

open(unit, file=*, status=’OLD’)

will display the standard file dialog for opening a file and assign the selected file to the Fortran unit number;

C 4

open(unit, file=*, status=’NEW’)

of course, will display the ‘Save File’ dialog and have the user input the file name. The actual file name, if needed, can be obtained through the Fortran INQUIRE statement. By default, files are of type ‘TEXT’, creator ‘MPS ‘; this can be changed through the keywords CREATOR and FILETYPE in the Open statement. The latter keyword also changes the files displayed in the ‘Open File’ dialog.

Many other keywords have been added to the Open statement, some of which have no effect at all, but ensure compatibility with other Fortran dialects (e.g. VAX) that use them.

Cross-language calling and COMMON access

Most of the remaining routines which display the data, play around with the output windows, and change some parameters, require no comment; However, I added one subroutine which calls a Pascal procedure, which in turn accesses the Fortran COMMON.

Calling a Pascal procedure from Fortran is easy; you simply declare the routine PEXTERNAL and pass the parameters in the same order as in the Pascal declaration. The default parameter passing is by value, references to variables can be passed by writing %ref(param). The Pascal procedure (Listing 2) receives a window pointer and a string, and displays the string in the window.

The window pointer - in our particular example - is also accessible through a named COMMON block, /windows/. The old LS Fortran allocated common memory dynamically, i.e., when a common block was first used, a heap object of the size of the common was created. This method still exists in Fortran 2.0; if you compile a program with the -dyn option, common blocks are created dynamically on the heap. However, with MPW 3.0 it is possible to use the linker for keeping static common blocks in the global data area. Fortran 2.0 programs compiled under MPW 3.0 will automatically static commons, unless you use the -dyn option.

The -f option in the MPW Link command causes the linker to treat duplicate definitions of a global data block as references to the same data block; thus, common blocks from different modules that have the same name will be automatically mapped onto each other.

All we need to do to access a static Fortran common from Pascal is to create a global variable with ‘the same name’ as the common block (thanks, Claudia Vaughan, again). ‘The same name’ has a particular meaning: Fortran names are uppercased for the linker, and COMMON names are enclosed between underscores; thus, the /windows/ common block is called _WINDOWS_ in the link map. The Pascal routine must define a global variable named _WINDOWS_, and the compiler must be told by the {$J+} directive that global variables may be defined externally. We define _WINDOWS_ as a global Pascal record having the same fields as the common block in the Fortran program, so that all common variables can be accessed conveniently through the fields of the record.

The Fortran version that I used still had some problems with dynamic commons, so that I couldn’t try out the old strategy to access COMMONs from Pascal using the run time library routine COMMONADDRESS; dynamic Fortran handling will work in the released version, as LS assured me.

More extensions

Language Systems have gone to great lengths to make sure compatibility of their Fortran with most mainframe implementations, notably VAX Fortran. Apart from the extensions I already mentioned, you can now omit arguments from subroutine calls (an integer*4 zero is pushed on the stack for each omitted argument), you can initialize data in the type declaration (real*4 x/4.0/ is a legal construct), BYTE may be used instead of INTEGER*1, and all the VAX keywords in I/O statements are recognized as syntactically legal. NAMELIST and ENCODE/DECODE also have the same syntax as on the VAX. Even the IOSTAT error codes have been changed to be equal to the corresponding VAX error numbers, where applicable.

What this means in practice is that you can take almost any code that runs on a VAX, feed it unchanged to the Language Systems compiler, and it will not just swallow it without complaints, but in most cases produce an application that produces the same result as the VAX program. In fact, the efforts for VAX compatibility have been extended to the point where Language Systems is encouraging third-party developers to create libraries that emulate VAX system calls, which would make the compatibility even closer.

I’d like to conclude with some remarks on the excellent manual; its format has been changed, starting with general remarks on how to get a Fortran program to run under MPW, and putting the formal language definitions to the end of the text. The MPW introduction has obviously been written by someone who exactly understands the difficulties that the average mainframe Fortran person would have dealing with such a bizarre object as the Macintosh and MPW running on it. I quote: “Using the Directory command. Type the line DIRECTORY. Then press the enter key (not the return key).” Just one example (there are many more) for the attention that the manual writer has given to the details.

In summary, the Fortran that combines ease of porting from mainframes with easy user interface creation, full Toolbox access and speed seems to have finally arrived. Expect to hear more of it later. We’ll continue next month with C++, and even some Forth again (!). Till then.
