Also, lost software. No longer at hobbes and and other sites.
OS/2 API Trace is a freeware application written by an IBM software engineer with extensive experience in OS/2 kernel and Presentation Manager development.
OS/2 API Trace allows you to trace the 16-bit and 32-bit OS/2 APIs used by any application running on any 32-bit version of OS/2 (2.0 or later) without requiring the application's source code or requiring the application to be recompiled/relinked. Simply enable the application for tracing and run it, and the OS/2 API calls (and optionally their parameters) made by the application are logged to a text file that is already formatted and in English. OS/2 API Trace also allows tracing to be customized, controlled, and summarized.
