Hi Steve,

The code you posted provides two functions, "AsciiToEbcdic()" and
"ebcdicToAscii()".  In particular, asciiToEbcdic() looks like a function
that can take a line of ascii, and convert it to a line of ebcdic.  So as
long as you're working with a single line of something, you should be able
to directly apply those functions.

Ah, ok.  Have you ready about how to apply some kind of process across a
file?

If not, you may want to look at:

which explains how to apply a process across a sequence, as well as:

for some examples of file manipulation.
