What is the correct structure for the input data in TXT format ?

[Adriano Bassignana]

What is the correct structure for the input data in TXT format. I can not put more than one channel. When I insert more than one channel, write the two columns side by side. But in this case the program does not seem proper values​​. For example, the TXT file is written in the following form:

123.456 789.101

234.567 890.123

....

The values ​​123,456 and 234,567, must be of the first channel, the values ​​789,101 and 890,123, must be of the second channel.

What is the correct way to operate?

Thank you :)

I'm doing some tests and looking into the scope of this problem. At this point it appears that a change or a bug was introduced in a standard system I/O library.

What operating system vendor and version are you using?
