1. NAME AND TITLE

DATINIT: Interactive Program To Access Photon Interaction Data.

DATA LIBRARY

PHOTON.DAT: Photon Interaction Data Extracted From DLC-99/HUGO.

2. CONTRIBUTOR

Australian Radiation Laboratory, Yallambie, Australia.

3. CODING LANGUAGE AND COMPUTER

Fortran 66; Data General Eclipse MV/family Computers (P00258DGMV100).

4. NATURE OF PROBLEM SOLVED

DATINIT provides access to photon interaction data from within a Fortran program for efficiency in a mini-computer environment.

5. METHOD OF SOLUTION

From the primary photon interaction data file of DLC-99/HUGO, 100 separate data files were extracted, one per element. The user must write a driver program for DATINIT to extract the data of interest. The extracted photon interaction data are written to a disk file named 'Znnn_aa.PHOTON.DAT', where nnn is the 3-digit atomic number and aa is the character symbol for the element.

6. RESTRICTIONS OR LIMITATIONS

Because this code is interactive and uses Data General system routines, its transportability is limited.

7. TYPICAL RUNNING TIME

The run time depends on the number of elements to be processed. Extracting one element only takes a few seconds.

8. COMPUTER HARDWARE REQUIREMENTS

DATINIT runs on Data General Eclipse series computers. It was developed on a MV/8000 and tested at RSIC on a MV/4000 under AOS/VS.

9. COMPUTER SOFTWARE REQUIREMENTS

Data General's Fortran 5 compiler is required.
