Cim 3.33 for MS Windows
CIM is a free Simula compiler developed by Sverre Johansen for Unix platforms. You can learn more in the CIM
I took Sverre Johansens sources, adjusted it little bit and compiled it for MS Windows 95/98/NT. You can use the compiler also with some newer MS Windows version, however you have to set up the environment manually.
History: CIM versus PC-Simula
I had problems with lack of memory for my Simula programs compiled under PC-Simula. PC-Simula is a Simula compiler for MS DOS from Simula a.s. The problem was PC-Simula did not use extend memory. I was searching for another compiler. The result is here. There are these main differences between these two compilers:
I did this job in range of my studies at the Faculty of Mathematics and Physics at Charles University in Prague in years 1994-2000, under the leadership by RNDr. PhDr. Eugene Kindler, CSc..
- CIM is free software (GNU).
- Compiled binaries can use virtual memory.
- Class Terminal (known from PC-Simula - character oriented GUI and
semigraphics) concludes also mouse control and many new functions.
- Graphics is not yet supported.
- From my personal experience (not a general rule) the programs compiled
under CIM are about 20% faster and if I use the 'strip.exe' (from mingw32)
the code (exe file) is about 50% smaller.
- There are some non-Simula restrictions for 'CIM programs' (e.g. only specified virtual
procedures can be used). The restrictions can be found in the CIM
