NCL is a powerful, structured high-level language that simplifies the development of
management applications. NCL enables programmers and expert operators to rapidly
develop applications that include such features as the following:
Menu-driven, multicolor, full-screen interfaces on Tandem 6530 terminals (does
not support color), IBM 3270 terminals and IBM-compatible personal computers
that emulate Tandem 6530 or IBM 3270 terminals
The ability to read data from and write data to sequential or indexed files; data can
include historical messages and other information
Communication with other NCL or non-NCL management applications that run
on Tandem or IBM nodes
Replacement of commands with NCL procedures that perform customized
functions, such as restricting use of a command to a specific time window
NCL is designed to address the specific needs of operations management. The
language includes verbs and built-in functions with which procedures can:
Access and manipulate operator display characteristics
Route messages to other operators
Access data files that contain operations information
Check the command authority level of another operator
NCL simplifies the use of the Tandem Distributed Systems Management (DSM)
architecture. By using such verbs as EMSREAD and EMSSEND, programmers who
know little or nothing about tokenized buffers can write NCL procedures that initiate,
receive, and process EMS messages.
For a comprehensive look at NCL, refer to the NonStop NET/MASTER NCL
Programmer’s Guide and its companion manual, the NonStop NET/MASTER NCL
Reference Manual.
