Raphael -  

There might be better ways, but I've been using this method for many years.  See code below. Some key items:

Use OUTPUT to redirect print statements.

The file is CSV only because the print statments include a ' , ' as a seperator.

I use the append mode because the first thing to go into the file is the lens name, then each print statement is appended.

I convert the file from unicode to ANSI. Matlab and other programs handle ANSI text files better, or least that was true.

Best regards,

John
