I think EBCDIC is going to be a pain. For one thing, many mainframe systems assumes fixed length records with no newline separator. I thought that different mainframes would use different characters to determine a newline. \x15 and \x25 are two that are used. Also, according to the documentation for Convert::EBCDIC, there is a standard EBCDIC and a version used for OS390 (which may account for the different line endings).

One problem there is that the EBCDIC Newline doesn't really translate to the ASCII CR or LF. Further, since the 'newline' varies on ASCII systems, I can only imagine that it's going to vary on EBCDIC systems. Admittedly, it's been a while since my mainframe days (no, I wasn't a Y2K boy), but I doubt you'll find a truly universal solution without the user choosing how their newline gets translated.

Here's an interesting chart of the EBCDIC characters. What the heck is a "Required newline" (\x06)? I sure as heck don't remember that.

Good luck.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
