The Fortran library TTUTIL
The model SWAP uses the Fortran library TTUTIL for input from files.
The Fortran library TTUTIL is a collection of
subprograms dealing with often returning problems like input from file, output
to file, character string handling, string decoding, file name and unit number handling,
date/time handling and more.
