PASCAL is the machine readable version of the well known French abstract journal Bulletin Signalètique. This article describes the primary sources, the file structure and all the data elements of a record. It reviews the inverted fields and the way to search them with the QUEST Software of ESA/IRS (European Space Agency/Information Retrieval System) and outlines the software possibilities (truncation, masks, conceptual logic, online ordering of original documents, etc…). Several examples of searches are given.
