5.24 OP,REST (RESTART)This option causes a set of matrix elements to be read from file TAPE2 which then replaces the set definedby the input to ME for the current job. This option enables continuation of a minimization or performingmost other operation using the latest set of matrix elements instead of the one appearing in the ME setup.Note that each OP,MINI command causes its final set of matrix elements to be written on file TAPE2. IfOP,REST is used it should immediately follow OP,YIEL.OP,REST provides the possibility to manually overwrite some of the matrix elements stored on TAPE2for the current job. This feature can be the useful time-saver when, for example, better estimates of somematrix elements have been found during a preliminary diagonal errors calculation. The input to OP,RESTshould be given as:OP, RESTI 1 , V 1 Index of the matrix element ( according to the sequence of ME )I 2 , V 2 to be overwritten ( I ) and its new value ( V ).·0, 0 Two zeros terminate input.Example:OP, REST0, 0 This sequence leaves the values stored on TAPE2 unchanged.102
5.25 OP,SIXJ (SIXJ SYMBOL)This stand-alone option creates a 6-j table to be used by the quadrupole sum-rules program SIGMA (seeChapter 6). OP,SIXJ is not related to an investigated nucleus, thus it can be inserted anywhere in the inputstream, even as the only option command. The output is written to a file TAPE14. No further input isrequired.Note: The execution of OP,SIXJ will cause GOSIA to stop the job after the 6 − j symbol table has beenwritten. The remainder of the input will be ignored.103
