This is probably a problem with the text file. Did you check that the
decimal mark was a dot (.) and not a comma (,) ? If it comes from Excel,
check that there is no empty cells. Make a try with a small text file
(just 5 lines and 2 or 3 columns). Try to use ADETrans.exe instead of
TextToBin.exe. Try to use the data sets provided with the WinPlus
interface to check that your installation of ADE-4 is correct.

You must also set the minimum and maximum of abscissa and ordinates to
(-1,+1),(-1,+1) in the "Min & Max" window (in the "Windows" menu).

Note that you probably don't want to use a correlation circle if you are
doing a correspondence analysis.

Sorry, I don't understand what you mean. I leave this one to someone else...

At which moment does it quit ? How many rows and columns does file.bin have ?
Are you sure that CategVar.exe runs fine ? Check the output files.
