FILE STATUS <name of Survo data file> displays the structure of a data file in the edit field from the last non-empty line onwards. The status is given as a table according to the format used in FILE CREATE and FILE UPDATE operations. Thus when updating data files, it is typical to use FILE STATUS first. Then it is easy to make the changes required and alter FILE STATUS to FILE UPDATE before reactivation. FILE STATUS shows all active fields by default and all fields by ALL=1. FILE STATUS also offers a basis for creating new data files of related structure. FILE STATUS also gives the status of each field after the type (N or S) in the form AB where A tells the activation status and B the protection status (- or P) of the field. The third status byte (scale type of variable) is not normally shown. However, this and other optional status bytes can be seen in the FILE STATUS table by activating it in the form FILE STATUS <name of Survo data file>,<# of status bytes> S = File status in a short form T = FILE STATUS for single variables with a given mask D = More information on data management
