Automatisation of chronic toxicities.

Automatisation of collection and processing of chronic toxicity tests are presented in a 'pharmaceutical research center environment'. The data are either analog signals or numerical values transmitted to the computer, from terminals posted in various laboratories. The minicomputer works under time-sharing system which allows many users to access to the programs in the same time. This system controls about 3000 results a day and prints complete reports in less than two days. Rewriting is then avoided thanks to this system, and in such a way, the reports are more reliable.
