(Character parameter; d/f= xronos)
Specify the filename root which is used by XRONOS applications to generate the default output filename. The default is xronos; e.g. running application lc1 the default output filename will be xronos.qlc1. Note that if default is specified as filename root, then the filename root will be the filename root of the 1st input file (e.g. running application lc1 with a2030.rbf as input file will cause the default output filename to be a2030.qlc1).
