Append files using TEXT_IO

Subject: Appending to files using TEXT_IO...

We have a requirement to determine if a file exists within
the current users directory.  If the file does not exist
we create if and log network transactions to it.

However if the file does exist we wish to log network
transactions to the end of the existing file.  Using TEXT_IO
there are a number of procedures which manipulate files
such as RESET, SET_LINE_LENGTH, SKIP_LINE, etc.  There
is no straight forwared procedure for OPEN_APPEND.  

We are seeking out projects which have solved this problem
before and come up with a clean way of opening a file
within the TEXT_IO package and appending to the end of it.

Thanks in advance,
