New data can be appended to the end of the existing --- file, and the same file can be reset to allow reading of data from --- the file. This process can occur multiple times. --- When the mode of the file is changed with a Reset, the current mode --- value assigned to the file is checked using the result of function --- Mode. This, in conjunction with the read/write operations, verifies --- that a mode change has taken place on Reset. --- --- An expected common usage of the scenarios found in this test would --- be a case where a single data file is kept open continuously, being --- reset for read/append of data. For systems that do not support a --- direct form of I/O, this would allow for efficient use of a sequential --- I/O file. --- --- APPLICABILITY CRITERIA: --- Applicable to all systems capable of supporting IO operations on --- external Sequential_IO files. --- --- --- CHANGE HISTORY: --- 06 Dec 94 SAIC ACVC 2.0 --- 19 Feb 97 PWB.CTA Fixed handling for file non-support and Reset --- non-support. ---! - -with Sequential_IO; -with Report; - -procedure CXA8002 is - subtype Employee_Data is String (1 .. 11); - package Data_IO is new Sequential_IO (Employee_Data); - - Employee_Data_File : Data_IO.File_Type; - Employee_Filename : constant String := - Report.Legal_File_Name (Nam => "CXA8002"); - - Incomplete : exception; - -begin - - Report.Test ("CXA8002", "Check that resetting a file using mode " & - "Append_File allows for the writing of " & - "elements to the file starting after the " & - "last element in the file"); - - Test_for_Sequential_IO_Support: - begin - - -- An implementation that does not support Sequential_IO in a particular - -- environment will raise Use_Error or Name_Error on calls to various - -- Sequential_IO operations.
