Echelon Neuron - Manual (Page 13)

• Chapter 8, System-Provided Functions, describes system-provided
functions for various arithmetical or logical operations or for stack
management.
This book also contains several appendixes with additional information.
Neuron Assembler Tools
You can create and edit Neuron assembly language files using any text editor,
such as Windows Notepad. The primary tool for working with Neuron assembly
language files is the Neuron Assembler. The Neuron Assembler translates your
source code, written in the Neuron Assembly language, into a Neuron object file
(.no extension). You can use the Neuron Librarian to create or manage code
libraries of Neuron object files, including those created from assembly language
files.
In general, you do not need to use the Neuron Assembler when creating a small
number of utility functions for use with one specific Neuron C application. To use
assembly source code within a Neuron C application, the Neuron C Compiler
supports the #pragma include_assembly_file directive, which can be used to
copy a specified assembly source file directly into the compiler-generated output.
The main tools for working with Neuron C applications, which can interact with
Neuron assembly functions, are the IzoT NodeBuilder FX Development Tool, and
the FT 6000 EVB. The IzoT NodeBuilder FX Development Tool can produce
Neuron assembly listing output files for your Neuron C programs.
Neuron C Compiler for Assembly Programming
The Neuron C Compiler supports the #pragma include_assembly_file
directive. This directive can be used repeatedly within the same Neuron C source
code, specifying one assembly source file at a time.
The Neuron C compiler translates your Neuron C source code into Neuron
Assembly output. When it encounters the #pragma include_assembly_file
directive, the compiler copies the content of the referenced assembly source file
directly (without modification) into its own output stream.
See the Neuron C Reference Guide for more information about compiler
directives.
Neuron Assembler Command Line Tool
The Neuron Assembler, available from the command line as NAS.EXE,
translates source files written in the Neuron assembly language (typically using
a .ns file extension) into Neuron object files (.no file extension), which can then
be packaged into function libraries using the Neuron Librarian (NLIB.EXE).
The resulting function libraries can then be provided to the Neuron Linker
(NLD.EXE), and code that is contained in these libraries and referenced by the
Neuron C source code is linked with the application.
To run the Neuron Assembler, open a Windows command prompt (Start →
Programs → Accessories → Command Prompt), and enter the following
command:
nas –switches file.ns
