When MORSE is run, the driver table (morse.drv) is always required. Additional input files are specified within various sections of the driver table.

Notes

  1. Most locally-defined input files start with an arbitrary number of optional comment records, identified by the first character being '!'
  2. Blank records are ignored
  3. Numerical data are read free format unless otherwise specifed and text data is read either from specific positions within record or using spaces to distinguish fields (essentially free-format but without any requirement for quote marks around character fields).
