With READ_ASCII and ASCII_TEMPLATE you can only read in the entire
file. Afterwards you can then select the 31st column. Unless you put a
special ASCII character before the 31st column and use that as your
delimiter in ASCII_TEMPLATE.

I suggest you read about READF and format codes.

Perfect solutions if your goal is to write the slowest
possible code. :-)

It's a possibility...

And using READ_ASCII and ASCII_TEMPLATE, any suggestions ?

I think you'd be better off using READF.
