About this manual

frontcover 72-TDS-367-01

This manual is the Toolset Reference Manual to the occam 2 toolset.

The manual provides reference material for each tool in the toolset describing:

  • Command line syntax, including an example command line.
  • Command line options.
  • How to run the tool.
  • A list of error messages which may be obtained.

Many of the tools in the toolset are generic to other INMOS toolset products i.e. the ANSI C and FORTRAN toolsets and the documentation reflects this. Examples are given in C.

The appendices provide details of:

  • Toolset conventions.
  • Transputer types.
  • Server protocol.
  • ITERM files.
  • Bootstrap loaders.
