RSIC COMPUTER CODE PSR-087

1. NAME AND TITLE

LIBMAK: ANISN-Type Binary Data Processing Code System.

2. CONTRIBUTOR

Plasma Physics Laboratory, Princeton University, Princeton, New Jersey.

3. CODING LANGUAGE AND COMPUTER

Fortran IV; IBM 360/370.

4. NATURE OF PROBLEM SOLVED

LIBMAK manipulates ANISN-type binary libraries. Input data may be taken from old libraries or card decks in AREAD (FIDO) format. Commands are available to create, revise, combine, list, and punch data stored in the standard ANISN format.

5. METHOD OF SOLUTION

The manipulation of the libraries by LIBMAK is a straight-forward bookkeeping job governed by input control cards. The routine AREAD is used to allow free-format specification of new data arrays and revisions.

6. RESTRICTIONS OR LIMITATIONS

The maximum library array size which can be handled is set by the dimensions of four internal storage arrays. A version of LIBMAK large enough to process the DLC-2 library (with arrays dimensioned 100 by 103) requires about 260 K bytes on an IBM 360/370 computer.

7. TYPICAL RUNNING TIME

On the IBM 360/91, eight DLC-2 type arrays were read by AREAD, listed, and added to a library in 12 seconds.

8. COMPUTER HARDWARE REQUIREMENTS

LIBMAK is operable on the IBM 360/370 computers.

9. COMPUTER SOFTWARE REQUIREMENTS

A Fortran IV compiler is required.
