        !            19: Several Fortran to C converters commercially available, but
        !            20: none are useful for projects bigger than a few hundred lines;
        !            21: their error rates are measured in percents.
        !            22: For large-scale conversions, error rates near one in a million are needed.
        !            23: Having a reliable Fortran to C converter is of immense interest and value
        !            24: to our research, where we mix Fortran and C in various environments
        !            25: and architectures.
        !            26: .PP
        !            27: We will produce a Fortran 77 (f77) to C converter this summer,
        !            28: with the aid of a summer student, Mark Maimone, from Carnegie-Mellon University.
        !            29: The program will be based on the original f77 compiler written by S. I. Feldman
        !            30: many years ago and still in heavy use.
        !            31: .PP
        !            32: That compiler internally constructs a C parse-tree and then produces C
        !            33: intermediate code for the second pass of the C compiler.
        !            34: We will produce a C program from the internal C tree.
        !            35: .PP
        !            36: Feldman's collaboration in this project makes it possible \(em
        !            37: there is nothing like having the author of a program advise on its
        !            38: alteration.
        !            39: We expect to have the converter running in a matter of weeks.
        !            40: Since Feldman is at Bellcore and the work will be done at AT&T Bell Laboratories,
        !            41: we propose to put the resulting f77 to C converter software in the public domain.
        !            42: This will be accomplished by putting the program and its documentation
        !            43: through a publication release, from both AT&T and Bellcore.
        !            44: .PP
        !            45: .B
        !            46: This note is to advise the relevant parts
        !            47: of AT&T of the project and prepare the way for the subsequent release
        !            48: of the software and documentation.
