File control system for history information

Abstract

Abstract PURPOSE:To eliminate the need for the update source text extraction processing by a compiler, and to shorten a compiling processing time by controlling individually, a source text and history information. CONSTITUTION:When the source text is read out of a history file 5, the pointer (starting address) of a source member 6 corresponding to a necessary source member name is read out of a directory part 9 firstly to access the source member 6, and text data is then stored in a compile input file. When history information is fetched, the pointer of a control member 7 is read out of the directory part 9 by a control member name to search for the source member name in the control member 7. Then, when a coincidence with the source member name is obtained, serial numbers of histories are read out and converted into history member names, which are used to search for the history member names in the directory part 9; and the pointer to the corresponding history member 8 is read out to fetch the history information in a working file.
