Write data to .txt file with formatting

Question

Hi,
I am trying to read data from serial port and write it on to a .txt file. I am able to write onto the file but it has got no formatting. What I would ideally like to do is, read the data from serial port, take only some parts of it and write on to the text file with proper formatting. Also, I would like to use the same file to append data each time. I am also having issues setting the pointer to EOF. I would like to append to end of file.
This is my sample data
18:33:23 02/10/10 28.32             0 LAC     0.378 mg/dL    0000\
18:33:23 02/10/10 28.32             0 GLU       102 mg/dL    0000
that is being read from the serial port. From this I would like to take only columns 1,2,3,5,6 and write onto the .txt file.
Can someone provide some pointers? I'm using Labview 6.1
Thanks,
Sukanya

If you know what "charecters" you don't want it is pretty easy. A little more difficult when they are unwanted only in certain places in the string. There is a remove whitespace function in the string functions palette. There is also a search and replace function in the "additional string functions" subpalette, that can be set up to find all instances of a char and replace it with something else, an empty string if you want to just delete it/them from your string.
