Keywords and input data formatting 143INTRODUCTIONHere after is given a detailed description of input data formatting and units. All available keywords appear in alphabeticalorder.Keywords are read from the input data file by an unformatted FORTRAN READ statement. They may therefore need beenclosed between quotes (e.g., ‘DIPOLE’).Text string data such as comments or file names, are read by formatted READ statements. Therefore no quotes are needed.Numerical variables and indices are read by unformatted READ. It may therefore be necessary that integer variables beassigned an integer value.In the following tablesthe first column states the input numerical variables, indices and text strings,the second column gives brief explanations,the third column gives the units or ranges of the input variables and indices,the fourth column indicates whether the inputs are integers (I), reals (E) or text strings (A). For example, ‘I, 3*E’means that one integer followed by 3 reals must be entered. ‘A80’ means that a text string of maximum 80 charactersmust be entered.
