Since some of Cobol data formats are not used by any other language or database, interpreting Cobol data is far from trivial. Again you need an FD/SELECT statement parser and record layout builder.įinally, once you have all file parameters and record layout, you need to read the actual Cobol data file and convert the record that you read to required non-Cobol format. You need to parse the extracted SELECT and FD statements and get file and record information from these statements. Therefore you need a specialized Cobol parser that does it. You need to extract SELECT and FD statements for the file from the Cobol program. This statement tells the system how the file record is organized: it contains record field lengths, offsets, usages, pictures, etc.Įven if you have all 3 components as described above, reading and interpreting the data is still difficult: It comes from the File Section of Data Division of the program that wrote the file. This statement tells the system how the file is organized: it contains file organization, file access mode, etc.įD statement for the file. It comes from the Input-Output Section of Environment Division of the program that wrote the file. That is, if you have just a Cobol data file and you do not have a Cobol program capable of writing or reading this file, you cannot correctly interpret the data contained in this file.įor every Cobol data file that you want to be able to read and interpret, you need the following: Also you may want to convert Cobol data files to modern formats such as CSV, DBF, Excel, Oracle, etc.ĭata Readers do just that - they convert Cobol data files to modern formats and make it available to programs in languages such as VB, C++, Java.Ĭobol data files do not contain information about their own organization and record structure. Today languages other than Cobol are often used for data processing and programs in these languages need to read legacy Cobol data files.
