QPATH <qpath> selects the path of another inquiry system. In Survo several inquiry systems may be maintained and used paral- lelly provided that different paths are provided for them. The path for the default inquiry system is given in the system file SURVO.APU as qpath=<default path> (qpath=C:\E\Q\EDQ for example). The three last characters (EDQ in the example) refer to a common forepart of all file names of the inquiry system and they are all standard edit files. The root file consisting of the keywords and their references to inquiry file has the name EDQ.EDT (or corresponding). To see the structure of various inquiry files, examine them, please. The QPATH operation can be used to change the inquiry system temporarily. C = More information on control operations
