A collection of tools, utilities and extra library modules extending the ordinary RAMSES release

What Is RAMSES Extras?

RAMSES Extras extends the ordinary release of RAMSES (Fischlin 1991 PDF). It is a collection of tools, utilities, and some less frequently used library modules nick named AuxLibExtra.

Most importantly, RAMSES Extras features the Modula-2 Mode for the great editor Alpha (for latest releases see here).

The RAMSES Extras is mainly targeted for the Mac Classic platform, but it contains several utilities which are of particular interest when porting your programs between the Macintosh and the IBM PC platform (see also Fischlin et al. 2006 PDF).

To learn about the formal interface, notably all functions of the AuxLibExtra see:

  • Overview of the AuxLibExtra modules.
  • Quick Reference containing all functions of the AuxLibExtra in a compact format.
