====== old index for f2c, now "readme from f2c" ============

FILES:

f2c.h    Include file necessary for compiling output of the converter.
    See the second NOTE below.

f2c.1    Man page for f2c.

f2c.1t    Source for f2c.1 (to be processed by troff -man or nroff -man).

libf77    Library of non I/O support routines the generated C may need.
    Fortran main programs result in a C function named MAIN__ that
    is meant to be invoked by the main() in libf77.

libi77    Library of Fortran I/O routines the generated C may need.
    Note that some vendors (e.g., BSD, Sun and MIPS) provide a
    libF77 and libI77 that are incompatible with f2c -- they
    provide some differently named routines or routines with the
    names that f2c expects, but with different calling sequences.
    On such systems, the recommended procedure is to merge
    libf77 and libi77 into a single library, say libf2c, to install
    it where you can access it by specifying -lf2c , and to adjust
    the definition of link_msg in sysdep.c appropriately.

f2c.ps    Postscript for a technical report on f2c.  After you strip the
    mail header, the first line should be "%!PS".

fixes    The complete change log, reporting bug fixes and other changes.
    (Some recent change-log entries are given below).

fc    A shell script that uses f2c and imitates much of the behavior
    of commonly found f77 commands.  You will almost certainly
    need to adjust some of the shell-variable assignments to make
    this script work on your system.


SUBDIRECTORY:

f2c/src    Source for the converter itself, including a file of checksums
    and source for a program to compute the checksums (to verify
    correct transmission of the source), is available: ask netlib to
        send all from f2c/src
    If the checksums show damage to just a few source files, or if
    the change log file (see "fixes" below) reports corrections to
    some source files, you can request those files individually
    "from f2c/src".  For example, to get defs.h and xsum0.out, you
    would ask netlib to
        send defs.h xsum0.out from f2c/src
    "all from f2c/src" is 652001 bytes long.

    Tip: if asked to send over 99,000 bytes in one request, netlib
    breaks the shipment into 1000 line pieces and sends each piece
    separately (since otherwise some mailers might gag).  To avoid
    the hassle of reassembling the pieces, try to keep each request
    under 99,000 bytes long.  The final number in each line of
    xsum0.out gives the length of each file in f2c/src.  For
    example,
        send exec.c expr.c from f2c/src
        send format.c format_data.c from f2c/src
    will give you slightly less hassle than
        send exec.c expr.c format.c format_data.c from f2c/src
    Alternatively, if all the mailers in your return path allow
    long messages, you can supply an appropriate mailsize line in
    your netlib request, e.g.
        mailsize 200k
        send exec.c expr.c format.c format_data.c from f2c/src

    If you have trouble generating gram.c, you can ask netlib to
        send gram.c from f2c/src
    Then `xsum gram.c` should report
        gram.c    fbc4f005    57277
NOTE:    For now, you may exercise f2c by sending netlib a message whose
    first line is "execute f2c" and whose remaining lines are
    the Fortran 77 source that you wish to have converted.
    Return mail brings you the resulting C, with f2c's error
    messages between #ifdef uNdEfInEd and #endif at the end.
    (To understand line numbers in the error messages, regard
    the "execute f2c" line as line 0.  It is stripped away by
    the netlib software before f2c sees your Fortran input.)
    Options described in the man page may be transmitted to
    netlib by having the first line of input be a comment
    whose first 6 characters are "c$f2c " and whose remaining
    characters are the desired options, e.g., "c$f2c -R -u".
    This scheme may change -- ask netlib to
               send index from f2c
        if you do not get the behavior you expect.

    During the initial experimental period, incoming Fortran
    will be saved in a file.  Don't send any secrets!


BUGS:    Please send bug reports (including the shortest example
    you can find that illustrates the bug) to research!dmg
    or [e-mail] .  You might first check whether
    the bug goes away when you turn optimization off.


NOTE:    f2c.h defines several types, e.g., real, integer, doublereal.
    The definitions in f2c.h are suitable for most machines, but if
    your machine has sizeof(double) > 2*sizeof(long), you may need
    to adjust f2c.h appropriately.  f2c assumes
        sizeof(doublecomplex) = 2*sizeof(doublereal)
        sizeof(doublereal) = sizeof(complex)
        sizeof(doublereal) = 2*sizeof(real)
        sizeof(real) = sizeof(integer)
        sizeof(real) = sizeof(logical)
        sizeof(real) = 2*sizeof(shortint)
    EQUIVALENCEs may not be translated correctly if these
    assumptions are violated.

    There exists a C compiler that objects to the lines
        typedef VOID C_f;    /* complex function */
        typedef VOID H_f;    /* character function */
        typedef VOID Z_f;    /* double complex function */
    in f2c.h .  If yours is such a compiler, do two things:
    1. Complain to your vendor about this compiler bug.
    2. Find the line
        #define VOID void
       in f2c.h and change it to
        #define VOID int
    (For readability, the f2c.h lines shown above have had two
    tabs inserted before their first character.)

FTP:    All the material described above is now available by ftp from
    research.att.com (login: netlib; Password: your E-mail address;
    cd f2c).  You must uncompress the .Z files once you have a
    copy of them, e.g., by
        uncompress *.Z

-----------------
Recent change log (partial)
-----------------

Tue Oct 15 10:25:49 EDT 1991:
  Minor tweaks that make some PC compilers happier: insert some
casts, add args to signal functions.
  Change -g to emit uncommented #line lines -- and to emit more of them;
update fc, f2c.1, f2c.1t, f2c.ps to reflect this.

Thu Oct 17 09:22:05 EDT 1991:
  libi77: README, fio.h, sue.c, uio.c changed so the length field
in unformatted sequential records has type long rather than int
(unless UIOLEN_int is #defined).  This is for systems where sizeof(int)
can vary, depending on the compiler or compiler options.

Thu Oct 17 13:42:59 EDT 1991:
  libi77: inquire.c: when MSDOS is defined, don't strcmp units[i].ufnm
when it is NULL.

Tue Oct 22 18:12:56 EDT 1991:
  Fix memory fault when a character*(*) argument is used (illegally)
as a dummy variable in the definition of a statement function.  (The
memory fault occurred when the statement function was invoked.)
  Complain about implicit character*(*).

Thu Nov 14 08:50:42 EST 1991:
  libi77: change uint to Uint in fmt.h, rdfmt.c, wrtfmt.c; this change
should be invisible unless you're running a brain-damaged system.

Mon Nov 25 19:04:40 EST 1991:
  libi77: correct botches introduced 17 Oct. 1991 and 14 Nov. 1991
(change uint to Uint in lwrite.c; other changes that only matter if
sizeof(int) != sizeof(long)).
  Add a more meaningful error message when bailing out due to an attempt
to invoke a COMMON variable as a function.

Sun Dec  1 19:29:24 EST 1991:
  libi77: uio.c: add test for read failure (seq. unformatted reads);
adjust an error return from EOF to off end of record.

Tue Dec 10 17:42:28 EST 1991:
  Add tests to prevent memory faults with bad uses of character*(*).

Thu Dec 12 11:24:41 EST 1991:
  libi77: fix bug with internal list input that caused the last
character of each record to be ignored; adjust error message in
internal formatted input from "end-of-file" to "off end of record"
if the format specifies more characters than the record contains.

Wed Dec 18 17:48:11 EST 1991:
  Fix bug in translating nonsensical ichar invocations involving
concatenations.
  Fix bug in passing intrinsics lle, llt, lge, lgt as arguments;
hl_le was being passed rather than l_le, etc.
  libf77: adjust length parameters from long to ftnlen, for
compiling with f2c_i2 defined.

Sat Dec 21 15:30:57 EST 1991:
  Allow DO nnn ... to end with an END DO statement labeled nnn.

Tue Dec 31 13:53:47 EST 1991:
  Fix bug in handling dimension a(n**3,2) -- pow_ii was called
incorrectly.
  Fix bug in translating
    subroutine x(abc,n)
    character abc(n)
    write(abc,'(i10)') 123
    end
(omitted declaration and initialiation of abc_dim1).

Fri Jan 17 11:54:20 EST 1992:
  Diagnose some illegal uses of main program name (rather than
memory faulting).
  libi77:  (1) In list and namelist input, treat "r* ," and "r*,"
alike (where r is a positive integer constant), and fix a bug in
handling null values following items with repeat counts (e.g.,
2*1,,3).  (2) For namelist reading of a numeric array, allow a new
name-value subsequence to terminate the current one (as though the
current one ended with the right number of null values).
(3) [lio.h, lwrite.c]:  omit insignificant zeros in list and namelist
output.  (Compile with -DOld_list_output to get the old behavior.)

Sat Jan 18 15:58:01 EST 1992:
  libi77:  make list output consistent with F format by printing .1
rather than 0.1 (introduced yesterday).

Wed Jan 22 08:32:43 EST 1992:
  libi77:  add comment to README pointing out preconnection of
Fortran units 5, 6, 0 to stdin, stdout, stderr (respectively).

Mon Feb  3 11:57:53 EST 1992:
  libi77:  fix namelist read bug that caused the character following
a comma to be ignored.

Fri Feb 28 01:04:26 EST 1992:
  libf77:  fix buggy z_sqrt.c (double precision square root), which
misbehaved for arguments in the southwest quadrant.

Thu Mar 19 15:05:18 EST 1992:
  Fix bug (introduced 17 Jan 1992) in handling multiple entry points
of differing types (with implicitly typed entries appearing after
the first executable statement).
  Fix memory fault in the following illegal Fortran:
        double precision foo(i)
*    illegal: above should be "double precision function foo(i)"
        foo = i * 3.2
        entry moo(i)
        end
  Note about ANSI_Libraries (relevant, e.g., to IRIX 4.0.1 and AIX)
added to README.
  Abort zero divides during constant simplification.

Sat Mar 21 01:27:09 EST 1992:
  Tweak ckalloc (misc.c) for systems where malloc(0) = 0; this matters
for subroutines with multiple entry points but no arguments.
  Add "struct memblock;" to init.c (irrelevant to most compilers).

Wed Mar 25 13:31:05 EST 1992:
  Fix bug with IMPLICIT INTEGER*4(...): under -i2 or -I2, the *4 was
ignored.

Tue May  5 09:53:55 EDT 1992:
  Tweaks to README; e.g., ANSI_LIbraries changed to ANSI_Libraries .

Wed May  6 23:49:07 EDT 1992
  Under -A and -C++, have subroutines return 0 (even if they have
no * arguments).
  Adjust libi77 (rsne.c and lread.c) for systems where ungetc is
a macro.  Tweak lib[FI]77/makefile to use unique intermediate file
names (for parallel makes).

Current timestamps of files in "all from f2c/src", sorted by time,
