Don't think so, at least not if you are using:
Open "Filename" for Input as #1
and
Open "Filename" for Output as #2
If you want to read some data, then write some data, then read some data, etc. you would probably want to read the whole file into an array (or some such container), close it, manipulate the array, then open the file again and write the data out.
If you have more specifics, I'd be glad to hear them...
