RSIC COMPUTER CODE PSR-036

1. NAME AND TITLE

CONVERT: An IBM-to-CDC Program Conversion Code.

2. CONTRIBUTORS

Los Alamos National Laboratory, Los Alamos, New Mexico.

Aerospace Research Applications Center, Bloomington, Indiana.

3. CODING LANGUAGE AND COMPUTER

Fortran IV and machine language; CDC 6600.

4. NATURE OF PROBLEM SOLVED

CONVERT looks for and flags or changes some of the Fortran differences in an IBM Fortran program in converting it for use with the CDC 6600 computer.

5. METHOD OF SOLUTION

CONVERT takes an IBM Fortran IV program as input and makes some of the necessary tedious changes arising from Fortran differences. Some statements that require change, but which are not changed by CONVERT, are tagged with the word FLAGGED for user action. Statements that are changed are tagged with the word CHANGED. No attempt is made to alter logic.

For identification, the cards within each routine are sequentially numbered, based upon the cards in the revised program output file. In addition to the numbers, each program, subroutine, and function has its own unique letter identification.

6. RESTRICTIONS OR LIMITATIONS

None noted.

7. TYPICAL RUNNING TIME

No study has been made by RSIC of typical running times for CONVERT.

8. COMPUTER HARDWARE REQUIREMENTS

CONVERT is operable on the CDC 6600 computer.

9. COMPUTER SOFTWARE REQUIREMENTS

A Fortran IV compiler is required.

11. CONTENTS OF CODE PACKAGE

Included are the referenced document and one (1.2MB) DOS diskette which contains the control cards, source code and sample problem input.
