1. NAME AND TITLE

PLOTENDF: A Program for Producing Graphical Output.

2. CONTRIBUTOR

CNEN - Centro di Calcolo, Bologna, Italy, through the NEA Data Bank, Gif-sur-Yvette, France.

3. CODING LANGUAGE AND COMPUTER

Fortran IV; IBM 370.

4. NATURE OF PROBLEM SOLVED

PLOTENDF produces graphical output of ENDF/B materials.

5. METHOD OF SOLUTION

Only file 3 (cross sections) is plotted; MT=1, 2, and 102 (total, scattering, and capture) are produced on a log-log scale. The remaining reactions are produced on a linear scale.

6. RESTRICTIONS OR LIMITATIONS

All sections must be in pointwise form (no resonance parameters). For this purpose, the RESEND code e. g. should be run before. All the materials of a given tape are plotted. When RESEND has not been run before, only the background is plotted.

The PLINE and BGNPLT routines have to be rewritten in order to run the program with a non-CALCOMP plotter.

7. TYPICAL RUNNING TIME

24 seconds for Uranium-238 (MAT=1262) on an IBM 370/168 under OS/MVS2.

8. COMPUTER HARDWARE REQUIREMENTS

PLOTENDF uses 120 kbytes of core memory, 1 tape unit, and a graphic device.

9. COMPUTER SOFTWARE REQUIREMENTS

A Fortran IV compiler is required.

10. REFERENCE

No formal report is available.

11. CONTENTS OF CODE PACKAGE

Included is one (1.2MB) DOS diskette which contains the source program and test-case data and output.

12. DATE OF ABSTRACT

September 1985.
