Introduction

The main functionality of the Telecom Engine is provided by external DLL function libraries which allows the Telecom Engine to interface with the operating system and various telecommunications hardware as well as providing sets of functions for task management, console terminal and logging, inter-task communications, string manipulation, TCP/IP socket connectivity, database access etc.

The language is fully extendable and new DLLs can be written to offer new functionality or to extend or replace the existing standard function sets.

The libraries belonging to the TE standard library set all have a name beginning with CX.
