Features of Server Library Programs

In most programming languages, server library programs can contain all the features of any ordinary program. What distinguishes a server library program is the inclusion of an export library, which is visible in most languages as an export list and a FREEZE statement. A server library program generally also includes features that specify the sharing and duration properties of the server library.

The following subsections outline the features required of server library programs in most languages, while also noting certain exceptions that apply to COBOL74 server libraries. The features of COBOL74 server libraries are most easily understood as a subset of the general server library features supported by the operating system.
