RSIC COMPUTER CODE PSR-081
1. NAME AND TITLE
FREEFORM: Free-Form Input Reading Routines.
Oak Ridge National Laboratory, Oak Ridge, Tennessee.
3. CODING LANGUAGE AND COMPUTER
Fortran IV and Assembler Language; IBM 360/370.
4. NATURE OF PROBLEM SOLVED
FREEFORM allows programmers to read input information without using FORMAT statements.
The input package consists of a set of three function subprograms which read real, integer, and
alphameric data, respectively.
5. METHOD OF SOLUTION
FREEFORM can be used to simply read cards containing numeric or alphameric information.
With the use of additional features and several other function subprograms, complicated input from any
type of device may be read and analyzed.
6. RESTRICTIONS OR LIMITATIONS
Each item in the input data should be separated from its neighbors by blanks. The input items may be continued on as many cards as necessary although a single item cannot be split between two cards.
If the IREAD function picks up a number with a fractional part, an error condition results and the
rounded number is returned.
7. TYPICAL RUNNING TIME
No study has been made by RSIC of typical running times for FREEFORM.
8. COMPUTER HARDWARE REQUIREMENTS
FREEFORM is operable on the IBM 360/370 computers.
9. COMPUTER SOFTWARE REQUIREMENTS
A Fortran IV compiler is required.
R. C. Durfee, "Fortran Free-Form Input," ORNL-Cf-70-1-45 (January 1970).
11. CONTENTS OF CODE PACKAGE
Included are the referenced document and one (1.2MB) DOS diskette which contains the source
code input, plus utility routines.
12. DATE OF ABSTRACT
January 1975; revised February 1984.
