There are many things that I could comment about in your code, but I don't have time to give you a tutorial.

However I'll suggest that the odds are very good that your bug is that you're misunderstanding the file format in some way. For instance it may be that the input you're getting doesn't use a standard return separator, so every way you have of reading it results in all of the data being put into one "line" with all of your versions of the program. Your parse program takes this data and then only reads the first line of data from it, and throws away as junk the rest of that "line" (ie the rest of your input).

To have any hope of helping you we'd need to know more about the format of the data.

An incidental tip. Fixed-format data formats are notoriously easy to mess up. I'd suggest that at least one of your fields have a "sanity check" that reports if it gets data that doesn't look reasonable. This will help you notice things like off-by-one errors.
