Abstract.
The 1966 ANSI standard FORTRAN specifies the input of numerical data only in fixed format. Described here is a scheme, written in ANSI 66 FORTRAN, which allows numerical data prepared in accordance with the FORTRAN 77 free-format specification to be read. In addition, the scheme is designed so that ill-formed or ambiguous data are given a reasonable interpretation and the location of the suspect data and the value assumed are identified.
