It must be noted that a repetition of a command may override an earlier occurrence of
that command.
Many commands provide the user with the opportunity to assign values to coefficients of
SWAN (e.g. the bottom friction coefficient). If the user does not use such option SWAN
will use a default value.
Some commands cannot be used in 1D-mode (see individual command descriptions below).

The command syntax is given in Appendix B.
Limitations:
• The maximum length of the input lines is 120 characters.
• The maximum length of the file names is 36 characters.
• The maximum length of the plot titles is 36 characters.
