A note about the future of ecsoft2.org

ecsoft2.org runs on software (Drupal 7 and PHP 7.4) that reached its end of life years ago and no longer receives security updates. Keeping the site online safely is getting harder.

Giving it a future means migrating it to a current platform — and that is only worth doing if people still use it and want to help keep it alive.

If you care about ecsoft2.org, as a user, a contributor, or someone willing to lend a hand, please ggambatiscali [dot] it (get in touch) by January 31, 2027.

If no one comes forward by then, the site will be turned into a read-only archive, so that its content stays available.

OS/2 Presentation Manager. A Programming Guide to Text, Graphics, and Printing - Graham C. E. Winn

This book is written for C programmers wishing to use the OS/2 Presentation Manager GPI and Dev functions for providing high quality text and graphics output to displays and printers. It is intended to be used along with the relevant IBM Reference Manuals and Online Reference, and is not a substitute for these.

This book, as far as possible, provides answers (illustrated by programming examples) to any questions that Application Developers may have concerning the GPI and Dev functions. Rather than providing a tutorial description, this book focuses on making the description of each topic as comprehensive as possible.
