You've found the internal read statement. Good, that's the most
important part of the answer. For the comma "problem", there are
several approaches.
1. In F2003, you could just add decimal='comma' to the READ statement. I
don't think that CVF supports that yet (it being a feature new to
f2003), but I haven't really looked and it is at least possible.
2. I assume that you already got the data into a character variable, or
know how to do so. (If my assumption is wrong, that's the first step).
Just find the commas and replace them with periods before doing the
internal read. The INDEX() intrinsic function can be used to find the
commas. This is probably the approach I would use (until the f2003
feature becomes widely available).
Lots of other ways are possible, but most are more complicated.
