[comp.lang.ada] VAX Extended Character Set

diederich_r_%ncsd.dnet@GTE.COM (Ray Diederich (301)-294-8400) (05/08/91)

Is there anyone out there who knows how to read text files containing
eight-bit characters using VAX Ada? I have used UNCHECKED_CONVERSION and
TEXT_IO to write eight-bit characters into text files, but attempts to read
any files with eight-bit characters causes a DATA_ERROR exception.

I've come across this problem several times over the past few years, and it
sure would be nice if I knew a solution.

Please send your responses to "diederich_r_%ncsd.dnet@gte.com"

Thanks in advance!

Well, to do this within the language, you'd have to define a 8 bit
character type and use sequential_io on it.  I doubt that this is
the answer you wanted to hear though...  -- Bud
