Encoding text file to appear on IBM Mainframe

I have a C++ program that sends data via FTP via ASCII mode to an IBM Mainframe. I am now doing this via C#.

When it gets there and viewed the file looks like garbage.

I cannot see anything in the C++ code that does anything special to encode the file into something like EPCDIC. When the C++ files are sent they are viewed ok. The only thing I see different is \015 & \012 for line feeds whereas C# is using \r\n.

Would these characters have an effect and if so how can I get my C# app to use \015?

Do I have to do any special encoding to make it appear ok?

Solution

  • It sounds like you should indeed be using an EBCDIC encoding, and then probably transferring the text in binary. I have an EBCDIC encoding class you can use, should you wish.

    Note that \015\012 is \r\n - they're characters 13 and 10 in decimal, just different ways of representing them. If you think the C++ code really is producing the same files as C#, compare two files which should be the same in a binary file editor.
