1.11 Output Information Major calculated results of the SRAC code are edited on a text-formatted file allocated to the 99th logical device. On the standard output file of the 6th device, information is written to check whether a series of calculations has completed appropriately or not, for instance, echo of user’s input, status of calculation progress, record of PDS file access, warning or error message. When the calculation finished normally, the following message will be appeared at the last of the above two files. '============================== END OF SRAC CALCULATION =======================' Otherwise, a user has to check the standard output carefully. For PIJ or PEACO, plotting options are available to confirm cell geometry under consideration or to draw hyper-fine neutron spectra obtained by PEACO. The plot data is written as a text-formatted Postscript file allocated to the 89th device. The user can see the figures of a Postscript file on a screen or printed matter, by using a free software on the market. On the UNIX operating system, a command ‘lpr’ is usually available to print out the figures. In the case of the burn-up calculation, editing of the calculated results in each burn-up step is repeated up to the final burn-up step on the 99th file. Its contents may be enormous to extract necessary data. Therefore, major burn-up parameters are summarized and tabulated to the burn-up step on the 98th text-formatted file. The binary data of fluxes and effective microscopic or macroscopic cross-sections are written in their own PDS files (cf. Sect.3.1). Although some of them can be printed on the 99th file by options, their printed format may not be convenient for plotting them or editing reaction rates defined by each user. In order to support editing or managing contents of PDS files, the SRAC system is equipped with several utility programs as described in Chapter 6. 27
