C C Description of data files: C C Input data WRIT to specify the names of the output files with the C computed quantities: C Data (1)-(5) common to all elementary waves should always be C located in the file specified by input SEP parameter C WRIT. C If optional input SEP parameter WRITEW=' ' (default), C data (6), repeated for all source points, should also be located C in file WRIT. C If optional input SEP parameter WRITEW is specified and is not C blank, data (6) for a single source should be located in file C WRITEW. C If there are several source points, data (6) are repeatedly C used for all source points. C The data are read in by the list directed input (free format). C The strings have thus to be enclosed in apostrophes. In the list C of input data below, each numbered paragraph indicates C the beginning of a new input operation (new READ statement). All C input variables, except K2P, are of the type CHARACTER. C The data are read by the subroutine WRIT1. C The filenames are generated using several components (strings) in C the following way: Each component (string) is divided into words, C each word being followed by just one space. Here a word is a C substring containing no space, preceded and followed by spaces or C by the beginning or end of the string. An empty word lies between C two consecutive spaces. The filename is composed of C the 1-st word of the 1-st component, C the 1-st word of the 2-nd component, C ... C the 1-st word of the last component, C the 2-nd word of the 1-st component, C the 2-nd word of the 2-nd component, C ... C the last word of the last component.
