Menus & Graphics in Release 0.95

A large number of internal changes were implemented in
this release, but first let's cover the user visible

1. MENUS! Popup menus are now supported, and are available
in sdesign with every Action field. In fact, any sdesign
field that is marked with a diamond graphic, has the
ability to popup a menu with F1 (or ^O).

2. To support menus, FUNCTION keys are now available in
Action mode (though CONTROL-O is an alternate way
of opening a menu). This included a new event
callback NC-FKEY-EVENT.... read more

0.92 Nearing Completion

Extensive work is being done within the CVS repository here as CobCurses gets reworked. It will be coming out with the GNU autoconf/automake tools, so that all you will have to do is:

make install

Stay tuned.

Bug in 0.90

For those trying to use release 0.90, be sure to update your cobcurses.c module before (re)building sd002. A bug snuck into it that causes the screen designer to hang when saving changes to the screen background.

The module cobcurses.c version 1.23 or later corrects this problem.

Thanks, Warren.

Beta Release 0.90 Available

Release 0.90 is now available. Check the notes and
change log attached to the download file. This
release should address many portability problems.

Portability Issues

There are a number of portability issues, even with the current release. If you are attempting to use this project on a platform other than Cygwin, or using the newer OC 0.33 compiler, expect to tinker with the code.

Roger While is gratiously helping me work through a number of these issues so that the next release of CobCurses will be portable to your platform of choice. I have also upgraded to the OC 0.33 compiler, allowing me to address some of the issues related to the compiler.... read more

Release 0.5 Available

This release has many small corrections and enhancements. Most notably the restricted character set functionality has been added. The 2nd most notable improvement is the inclusion of a User_Guide.pdf document to guide you through the process of generating a screen. Finally, there is now a template main and template screen pair of Cobol programs provided. These are a working example, but can be used as a prototype for your next screen.... read more

Much more complete documentation is now available in two formats: User_Guide.doc (MS-Word) or User_Guide.pdf.

This documentation supports the upcoming Release 0.5. You should find everything you need in the document with the exception that the CobCurses API is not yet documented. However, the API is easily discerned by examination of the copy books, if you need to.

Release 0.4 Available (almost Beta status)

Release 0.4 has a nearly complete Screen Designer 2.0 (the original has been retired, but was useful to bootstrap this project). SD002 now supports the creation/editing of screens, fields, screen backgrounds and field states. This appears to be stable now, and is quite usable in its present form.

Documentation is still lacking, but will be the next priority. Ironically, this will take longer to develop than the actual code ;-) Use the file QUICKSTART for introduction and module SD002010.cob as a sample application.... read more

Current Work

The project is still in alpha status. What I am trying to do however, is to bootstrap Screen Designer 2 (SD002) from the first one (SD001). SD001 is unforgiving and has some bugs, but if you're careful, it is useable.

SD002 will have a cleaner screen design and because it is partially generated, is more reliable and forgiving. I have also improved the screen code based upon experience gained from SD001.... read more

Release 0.03 fix & enhancements

Release 0.03 adds the missing Delete field capability that got overlooked.

Also included is a vastly cleaner status line API call and the event callbacks are now three. See the file HISTORY for the details.

Release 0.02 Available

Release 0.02 has the field state maintenance screen added. The BGGEN program now supports generation of all field state information.

CVS Repository has been loaded

I have uploaded the current state of the CobCurses project to the SF CVS repository. The screen generator is not yet complete, but those wishing to use Ncurses from Cobol will find most of what they need is supported.

The screen designer is able to generate screen background code and field configuration code. The major piece outstanding is the editing and generation of the field state tables.

IMPORTANT: The current project is only known to work with OpenCobol. Futhermore, the module cobcurses.c expects values in host endian order (little endian on Intel). Eventually cobcurses.c will be updated to handle OpenCobol's bigendian users.... read more
