plus<\/em>FORT Version 8 – Gets rid of ALL<\/span><\/em> GOTOs<\/h2>\nVersion 8 is our biggest ever update, and it’s\u00a0 free for personal, educational and academic users<\/span><\/strong><\/em> working on non-commercial projects.<\/p>\n\n- SPAG uses structure templates to unscramble spaghetti code. In earlier versions, there were three major templates:-<\/li>\n<\/ul>\n
\n- \n
\n- Block IF statements<\/li>\n
- DO loops with EXIT and CYCLE<\/li>\n
- Single statement code replication<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n
Version 8 adds two new templates which allow it to remove all GOTOs in even the most convoluted code. These are:<\/p>\n
\n- \n
\n- 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.<\/li>\n
- Internal Subroutines. SPAG identifies separately addressable code blocks, and relocates them into internal
\nsubroutines. Blocks are invoked in the correct order using CALL statements, and the calls may be recursive.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\nThese two new templates provide alternative ways to express the same control flow.\u00a0 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.\u00a0 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.\u00a0 Conversely, dispatch loops keep a strict cap on the complexity of more complex codes.<\/p>\n
Examples may be found in section 2.7.1<\/a> of the plusFORT manual.<\/p>\n\n- 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.<\/li>\n
- 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.<\/li>\n
- 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.<\/li>\n
- 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.<\/li>\n
- SPAG switches to “module-maker” mode when an INCLUDE file (no subprogram or END statement) is encountered.<\/li>\n
- Numerous bug fixes.<\/li>\n
- Manual updated to revision P.<\/li>\n<\/ul>\n
Free Academic & Trial Licences<\/h2>\n
A major update to plusFORT – version 8 – will be released in the first week of December 2023.\u00a0 With this release, we also plan some changes to our pricing and licensing:<\/p>\n
\n- With immediate effect, we are scrapping all licence fees for personal, educational and academic users. Eligible users can download<\/a> a fully functional, unrestricted version of plusFORT for non-commercial, non-government use.\u00a0 These licences may not be used to produce proprietary or closed source code or reports.<\/li>\n
- Commercial licence fees will be increased significantly, but not until January 2024. This provides an opportunity for users in business and government agencies to buy the new version at old prices. You may also buy maintenance (for multiple years in advance if required). To take advantage, please be sure to send your PO, or visit our online shop, and complete your purchase before the end of the year.<\/li>\n
- Fully functional commercial trial licences are now available on demand<\/a>.<\/li>\n<\/ul>\n
plus<\/em>FORT<\/strong> Version 7.60 – Fortran 2003 and More<\/h2>\n\n- Initial support for Fortran 2003. SPAG now supports input and output of Fortran 2003 syntax, including the object oriented programming features.\u00a0 There are some known limitations (documented in the READ.ME file).<\/li>\n
- \u00a0Revised code indentation scheme for free format source form
\noutput. Outdenting for suprogram, CONTAINS and END statements, and optional indentating for executable code relative to declarations.<\/li>\n - SPAG can now distinguish automatically between the traditional fixed form (72 characters, sequence numbers in columns 73-80), from the VAX source form (with TABs and longer records).<\/li>\n
- The default values for several SPAG configuration options have been changed.<\/li>\n
- Various bug fixes and minor cosmetic improvements to restructured code.<\/li>\n
- Manual updated to revision M.<\/li>\n<\/ul>\n
plus<\/em>FORT<\/strong> Version 7.50 – A Major Update<\/h2>\n\n- HyperKWIC can now be run directly from the PFFE graphical user interface.<\/li>\n<\/ul>\n

<\/a><\/p>\n <\/p>\n
\n- 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.<\/li>\n
- Improved formatting of declarations rewritten with Fortran 95 syntax\n
\n- 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.<\/li>\n
- SPAG inserts INTENT and OPTIONAL clauses within dummy argument declarations, rather than as separate statements.<\/li>\n<\/ul>\n<\/li>\n
- 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.

<\/a><\/li>\n<\/ul>\n <\/p>\n
\n- 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.

<\/a><\/li>\n<\/ul>\n <\/p>\n
\n- 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.<\/li>\n
- The default initial working directory for PFFE and the plusFORT Command Prompt have been set to the current user’s Documents directory.<\/li>\n
- Possible errors when rewriting declarations from scratch in an internal subprogram fixed.<\/li>\n
- The ability to switch off header comments by setting item 220 of SPAG configuration to blanks restored.<\/li>\n
- Many other minor fixes and enhancements.<\/li>\n
- Manual updated to revision L.<\/li>\n<\/ul>\n
plus<\/em>FORT<\/strong>\u00a0Version 7.25 – 64 bit Support<\/h2>\nVersion 7.25 is the first fully 64 bit version of plus<\/em>FORT,\u00a0 and in consequence, only 64 bit\u00a0 versions of Windows, Linux and MacOS are supported.\u00a0 In addition, PFFE, the plus<\/em>FORT graphical user interface has been substantially upgraded, and now supports context sensitive help for all configuration options.\u00a0 \u00a0Other fixes and enhancements are listed below.<\/p>\n\n- Full context sensitive help (using F1) in Windows and Linux versions of PFFE.<\/li>\n
- PFFE updated to deal gracefully with “starter pack” version.<\/li>\n
- Possible broken links in GXCHK hypertext reports fixed.<\/li>\n
- Substantial reorganization and re-design of PFFE forms and dialogs.<\/li>\n
- Fixed SPAG could put output files in wrong directory when input path contained spaces.<\/li>\n
- Fixed misleading message when plusFORT.fig not found.<\/li>\n
- Fixed bugs in cvranal and probes.f90 coverage analysis routines relating to paths with spaces.<\/li>\n
- Fixed bug in naming of MODULEs created to replace INCLUDE files with names (excluding path and extension) longer than 20 characters.<\/li>\n
- Fixed bugs in command line processing on Linux and Mac.<\/li>\n
- Big increase in command line buffer on Linux and Mac.<\/li>\n
- Numerous improvements in processing long paths with embedded spaces.<\/li>\n
- Fixed comments in source code between modules were sometimes lost.<\/li>\n
- Various minor fixes and enhancements.<\/li>\n<\/ul>\n

HyperKWIC is a tool for generating software documentation that combines the instant connectivity of hypertext with the analytical strengths of KeyWord In Context. It produces HTML documents that provide a fully interactive alternative to traditional documentation. HyperKWIC may be used to document source code written in Fortran, C, C++, Delphi or any other mainstream language.<\/p>\n
You can interact with sample HyperKWIC reports for large Fortran and C programs by clicking\u00a0here<\/a>\u00a0<\/span>and\u00a0here<\/a><\/span>. HyperKWIC reports can be viewed on any system with a reasonably capable web browser, including tablets and smart-phones.<\/p>\n
