If you've ever used dbaccess on Windows and have your Command prompt screen buffer height set to greater than the old default of 25 lines, you've probably seen the screen buffer corrupted after exiting from dbaccess. A typical symptom is getting a directory listing by running 'dir' and seeing the listing obscured by fragments of earlier screen output.
I'm pleased to report this problem is finally resolved, with the fix of product defect 175362:
DBACCESS CORRUPTS CONSOLE BUFFER WHEN EXITING ON WINDOWS
With the fix in place, the screen buffer is saved when dbaccess is started, and correctly restored upon exit. Look for this in the next IDS interim version, 10.00.TC5, or for those who can't wait, the fix is already available in the 10.00.TC4W2 post-interim drop.
So, you might be wondering, when is IBM going to offer a fully featured interactive GUI SQL editor for Informix?
There are some interesting projects currently underway in this area, I hope to provide more updates soon.
