Format-free input in FORTRAN

Format-free input in FORTRAN C. L. McCARTY, JR., Editor Format-Free Input in FORTRAN M. J. BAILEY, M. P. BARNETT .AND R. P. FUTRELLE Massachusetts Institute of Technology,* Cambridge, Mass. 1. Introduction Although the input statements of the FORTRAN language allow data to be punched in formats that are quite elaborate, these formats must be specified precisely by the user and then must be maintained in a consistent manner. The fate of each item of input depends on its precise position on a card, on the position of that card in a deck and on the completeness of the deck. The term format-free input may be used for data that is punched in arbitrary fields, and to an arbitrary number of figures. Several subroutines have been reported by other authors to deal with such input [1-5]. This note describes some further subroutines that deal with format-free input of several types. Format-free input may be order-dependent or orderindependent. A program that deals with order-dependent input must seek some predetermined number of items, that are delimited by blanks or commas or in other ways. The successive items that are found in a systematic scan then can be stored in addresses which are associated with the http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Communications of the ACM Association for Computing Machinery
