I am looking over Simula language to see how it compares to C++/Smalltalk, and I have two questions that are difficult to find answers to because each time I type in Simula into Google, it gets replaced by "C", "Python", or "Simulation".

  1. Was Simula case sensitive?

  2. What file extension was used for Simula programs?

  • The search term is "Simula 67" or "Simula I". Sep 2, 2017 at 18:33

Simula is case-insensitive.

=> Wikipedia

After taking a look at the sample content in Simula from this piece of documentation (download the ZIP folder to view content), the files are saved with either the .sim or the .pas extensions.

  • Ah my bad, I should have figured to check the zip files to test something like this. Now I know. Thanks for the quick response. Also worth noting even without Wikipedia, the zip file contains samples like SIM3.SIM which is all lowercase, and TESTFOR.SIM which has mixed case.

  • Actually, I wouldn't be surprised if Simula predates the concept of using part of the filename to tag a file with its content-type. Oct 14, 2016 at 23:36
