But character data is not the same thing as numeric data. Okay---

But it's topsy-turvy day! Didn't you get the memo?
Oh, all right. IEEEtoIBM it is.

Here's a quick attempt at converting doubles using Python.
It uses the isnan and isinf functions that

Whoops---wrong way around. It looks like it's IEEE that has the
larger exponent range. DBL

I don't know of anything in Python that does this. There was
a thread a while ago that may be relevant:

I'm poking at writing data out to a SAS XPORT file (transport file).
Each record must be 80 bytes long, ASCII. Integers should be "IBM-
style integers" and floats should be "IBM-style doubles." Now I have
some idea what that means from reading a C source file documented by
the SAS institute, but be
