Correspondence item: Design considerations for continuous system simulation languages

Currently available continuous system simulation languages (CSSLs) are reasonably effective in providing a more user-oriented interface to the computer. However, the fact that CSSLs represent a tool and not a panacea has not always been kept in perspective. Operational problems have hindered the use and consequent improvement of the languages. Designers and implementers must be willing to stay in the loop and smooth out the operational interface for the users. The future for CSSL is very bright. The increasing use and importance of remote, interactive terminals is based on the same user-problem approach that is the foundation of CSSL. It is in this area that CSSL will probably be most effective and will experience broad acceptance by new users.
