Operating System Conventions

For UNIX

This heading is used to indicate the start of a section of text that applies only to the HP-UX operating system.

For Windows

This heading is used to indicate the start of a section of text that applies to the Win32 client, which runs on the Microsoft NT (Version 3.51 or later) and Windows 95 operating systems.

SNAplus2 also provides a Win16 client that runs on Microsoft Windows 3.1 and Windows for Workgroups 3.11. The Win16 client is very similar to the Win32 client, except that you enable and configure the client software differently.

The APIs for the Win32 and Win16 clients are fully compatible with Microsoft SNA Server and Windows Open System Architecture (WOSA), enabling applications written for SNA Server to run unchanged on the Win32 and Win16 clients.

End of Section

This heading indicates the end of the operating system specific text. The information following this heading applies regardless of the operating system.
