3. DESCRIPTION OF PROGRAM OR FUNCTION

Retrieve EXFOR data according to a given target nucleus, reaction type, year range and incident energy range, convert them to a data-table form which can easily be processed further by computer.
[ top ]
4. METHOD OF SOLUTION

The program works on the basis of 3 dictionaries:
   - EXFOR reaction quantities
   - EXFOR data headings
   - EXFOR data units.
The program is therefore flexible and may easily be extended to more complicated EXFOR data formats.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

The input data file  must be correctly coded in EXFOR format.

6. TYPICAL RUNNING TIME

5 seconds on IBM 3081. The test problem requires 5.2 seconds on a VAX. The execution time depends on the size of the EXFOR input file and the arrangment of the dictionaries.

7. UNUSUAL FEATURES OF THE PROGRAM

Before running the program it is better to check whether the dictionaries include all the items needed at this time. If these items are placed at the beninning of the dictionaries, the program will run faster. If after running the  program some new items (heading & unit) are found in the report-listing, then update the dictionaries to add these items and  run the program again.
