ExceptQ Exception Handler v6.7 24 May 2008 This version has been replaced by a compatible version with enhanced output formatting. Download it from exceptq 7.0. Check for newer versions with Search.

ExceptQ is a generic OS/2 exception handler DLL. This version is based on code that appeared in the IBM Developer Connection magazine which appears to be in the public domain. This version corrects several defects in the original and contains reasonably clean 32-bit support. The original sources were probably written with CSet/2 and assume that they are compiled as 16-bit code.

This version also contains support for oversized (i.e. >64KiB) symbol files.

There are several other versions floating around the net. This version is based on source code delivered with an issue of the IBM Developer Connection magazine and has no known license issues. Some of the other versions were marked IBM Internal Use Only.
