What are SPARCworks, EOS, and WorkShop?
SPARCworks was a development environment from Sun (circa 1993-1996) and consisted of compilers (C, C++, FORTRAN 77, Fortran 90, Ada, and Pascal), a debugger, and other tools such as TeamWare (for configuration management), MakeTool, etc. EOS is the integration of XEmacs with the SPARCworks debugger. It allows one to use an XEmacs frame to view code (complete with fontification, etc.), set breakpoints, print variables, etc., while using the SPARCworks debugger. EOS stands for “Era on SPARCworks”; Era stood for “Emacs Rewritten Again” and was the name used by Sun for its modified version of Lucid Emacs (later XEmacs) in the early-mid 90’s. This is documented in more detail in the history section of the XEmacs About page. EOS was replaced around 1996 with a newer graphical development environment called Sun WorkShop. The current status of this is unknown.
