The management of processes and threads running in the system is
simplified and enhanced under OS/2 2.0 in the following areas:
- Support for processes running in real mode (such as the DOS box in
previous OS/2 versions) is no longer required.
- Support for DOS applications in DOS sessions that run in a protect
mode process.
- Protection exception management.
OS/2 2.0 supports the following types of applications on the desktop:
- 32-bit applications developed for OS/2 2.0
- 16-bit OS/2 applications developed for previous OS/2 versions
- DOS applications in full-screen mode or in a window on the OS/2
desktop
- Windows applications running in a WIN-OS/2 full-screen session or
in a WIN-OS/2 window session on the OS/2 desktop
Under OS/2 2.0, all applications run as protect mode processes.
Therefore, they are provided with preemptive multitasking and full
memory protection between processes. Refer to the OS/2 2.0 Master
Help Index for more information on Windows application support.
