Creating A Text File With Vba

each row in sheet1 contains variables that, when applied to cells in sheet2, calculate a final figure. I have written code that selects each row, distributes its variables in sheet2, and shows the result back in sheet1, then selects the next row, and so on until all rows have been calculated.

The calculation is complex, and I would like to create a text file that stores the calculation for each row in the same text file. The calculation is a 9 columns by 33 rows, and I would like to preserve this shape in the text file, though its OK not to have columns not lining up.

There is a similar problem on an old thread but this requires only one iteration of "open file, write values, close file". I need "open file, write values, write more value, close file".
