I'm trying to do the following. I create a filename then check if it exists, if it does, then i open it and set the file position to the end of the file. I then call a for loop which should write some values to it. However, if the file does not exist, i create it and set the file position to the end of the file and then add some header information to the file.
The problem is, that the file gets rewritten on each write!
If you delete the offset constant, the VI should work fine. If you look at the help of file position vi, you will see that the offset in bytes actually sets the file marker. if it is an existing file, you do not want to change this ever assuming your appending)
It does work, it just doesnot appear to work because of the way you are writing the file. Put an end of line constant at the end of the concenate string and run twice.
I added the end of line character to it, but doesnt seem to be working, what am i doing wrong? Furthermore, i cant open the file 'cos i have labview 8.0 and not 8.2.
