Summary: Appending (OPEN EXTEND) to a Sequential file created under DOS Version 1.x does not work. If a Sequential or Line Sequential file created by a program other than MS-COBOL Version 2.00 or later is to be OPENed with the EXTEND (append) option, the file must first be copied using one of the following methods: 1. A program written in MS-COBOL Version 2.00 or later 2. A utility that will produce a file with MS-DOS Version 2.00 end-of-file format Using one of these methods will ensure that the data file end-of-file format will be acceptable to MS-COBOL. For more information, see Chapter 7 of the “Microsoft COBOL Compiler User’s Guide.”
