In Mainframe Express, should files be stored in EBCDIC format or ASCII format?

Mainframe Express stores all data in EBCDIC, rather than the ASCII character set native to PCs. It is converted automatically between EBCDIC and ASCII for input/output, so that you see the correct characters on the screen or printout. In general, you can assume that in comparisons data will behave as on the mainframe. Mainframe Express also provides facilities for you to convert explicitly between EBCDIC and ASCII, if you should need to.
