plusFORT Version 8 - Gets rid of ALL GOTOs

Version 8 is our biggest ever update, and it's now free for personal, educational and academic users working on non-commercial projects. Just head to this page and enter your details to receive a free licence. Commercial users can go here to download a fully functional free trial version. Existing users with current maintenance can get their update here.

Version 8 Changes

• SPAG uses structure templates to unscramble spaghetti code. In earlier versions, there were three major templates:-

• Block IF statements
• DO loops with EXIT and CYCLE
• Single statement code replication

Version 8 adds two new templates which allow it to remove all GOTOs in even the most convoluted code. These are:

• Dispatch loops. SPAG identifies separately addressable code blocks (block 1, block 2 etc.), and relocates them into a SELECT CASE construct for execution in the correct sequence, under control of a dispatch loop.
• Internal Subroutines. SPAG identifies separately addressable code blocks, and relocates them into internal
  subroutines. Blocks are invoked in the correct order using CALL statements, and the calls may be recursive.

These two new templates provide alternative ways to express the same control flow. SPAG allows you to select either one, but the default is to use internal subroutines in simpler cases, where there is no recursion, and dispatch loops otherwise. In practice, internal subroutines are a natural way to express many simple cases, for example where a code fragment is used to tidy up before exiting a subprogram. Conversely, dispatch loops keep a strict cap on the complexity of more complex codes.

Examples may be found in section 2.7.1 of the plusFORT manual.

• Version 8 benefits from a major internal upgrade which removes a long-standing limitation to SPAG's symbolic analysis, allowing it to "look ahead", and reliably identify the characteristics of subprograms with and without explicit interfaces. This change has knock-on effects throughout SPAG and GXCHK, for example in improved reporting and error detection. It also enables new functionality both in this release and in the future.
• SPAG's prescan, which allows it re-order input files so that MODULES are processed before code that uses them without the use of makefiles or external props, has been extended and improved.
• SPAG now uses the standard ISO_FORTRAN_ENV module to allow it to translate legacy non-standard types, such as INTEGER*1 and REAL*8, to standard Fortran. This supersedes and improves upon the previous treatment using the proprietary F77KINDS module.
• By default, SPAG now inserts a PROGRAM statement at the beginning of code with no subprogram statement, and adds an invented name to un-named BLOCK DATA subprograms.
• SPAG switches to "module-maker" mode when an INCLUDE file (no subprogram or END statement) is encountered.
• Numerous bug fixes.
• Manual updated to revision P.

Neue Version 7.50

Polyhedron Solutions Ltd hat eine neue Version von plusFORT veröffentlicht. Diese erhalten die registrierten Nutzer im Rahmen ihrer Wartungsverträge über diesen Link. Diese sind auch über uns erhältlich. Details der Neuerungen:

Polyhedron Solutions has just released version 7.50 of plusFORT, the software engineering toolkit for Fortran programmers.

• Existing users with a current maintenance contract can download this new version here.
• If you would like to buy a copy, or renew maintenance, you can do that here .
• You can register for an evaluation version, with some limits on functionality here

A summary of the new features is presented below. We look forward to hearing your feedback. If you have an old version of plusFORT, we urge you to take a look at the exciting new features - like HyperKWIC and the new features to assist in modularization.

Version 7.50 A Major Update

• HyperKWIC can now be run directly from the PFFE graphical user interface.
  
  
  
  
• SPAG now re-orders input files to ensure that MODULES are processed before code that uses them. This ensures that SPAG has the information it needs to make a full and accurate analysis, and is most effective if all the source code of a program is analysed in a single run.
• Improved formatting of declarations rewritten with Fortran 95 syntax
  • SPAG writes dummy arguments in the order they appear in the argument list, rather than alphabetically. Each dummy argument is declared in a separate statement to allow end of line comments for each argument.
  • SPAG inserts INTENT and OPTIONAL clauses within dummy argument declarations, rather than as separate statements.
• GXCHK produces a new Internalisation Report, to help re-engineer legacy Fortran. It shows which subroutines and functions can be converted to internal subprograms, thus reducing the number of separate program units to be combined at link time.
  
  
• GXCHK produces a new Cluster Analysis Matrix report which identifies groups of subprograms which may, on the basis of data usage and calling patterns, to be candidates for inclusion in modules.
  
  
• The name of the HTML report porduced by GXCHK has been changed from gxchk.htm to _gxchk.htm for consistency with other plusFORT tools, and to make it easier to find.
• The default initial working directory for PFFE and the plusFORT Command Prompt have been set to the current User's Documents directory.
• Possible errors when rewriting declarations from scratch in an internal subprogram fixed.
• The ability to switch off header comments by setting item 220 of SPAG configuration to blanks restored.
• Many other minor fixes and enhancements.
• Manual updated to revision L.
