SET FILE/ATTR=REVDATE doesn't work?

CA1225221 — Wed, 13 Feb 2013 00:11:23 GMT

SET FILE/ATTR=REVDATE does not appear to work. The REVDATE ends up as the current date/time. It might be that the REVDATE is correctly set but then because the file was just modified, REVDATE is set again - thereby making the command pointless.

Is this just me?

Environment is Itanium, V8.4, ODS-2

NB: Changing to ODS-5 is *not* an option.

There appears to be an undocument /[NO]RECORD qualifier but it doesn't seem to make any difference.

   No. Same behavior on my "COMPAQ Professional Workstation XP1000
running OpenVMS V8.3". I know nothing, but I suspect that your analysis
is correct. <fabdef.h> mentions FIB$M_NORECORD and fib$v_norecord,
which can be used to access the magic bit. (It's used in Info-ZIP UnZip
[.vms]vms.c:stamp_file().)

   It looks to me as if it wouldn't actually help, either.

   Perhaps when someone gets it to work, it'll be documented.

Pretty dumb huh? I seem to recall someone even defending the behaviour.

Anyway.. Macro and Cobol workarounds by yours truly in answers to comp.os.vms topic "manually resetting file revision dates"

https://groups.google.com/d/topic/comp.os.vms/RPIayAr6Vm0/discussion

C workaround below.

Hein.

#include descrip
#include stdio
#include RMS
main(int argc, char *argv[])
{
    struct FAB fab = cc$rms_fab;
    struct XABRDT dat = cc$rms_xabrdt;
    int stat;
    int date_dx[2];

    if (argc < 3) {
        printf ("Usage: %s <file-name> <revision-date>\n", argv[0]);
        return 1;
        }
    date_dx[0] = strlen (argv[2]);
    date_dx[1] = (int) argv[2];
    fab.fab$l_fna = argv[1];
    fab.fab$b_fns = strlen(fab.fab$l_fna);
    fab.fab$b_fac = FAB$M_PUT;
    fab.fab$l_xab = &dat;

    stat = sys$open ( &fab );
    if (stat & 1) stat = sys$bintim ( date_dx, &dat.xab$q_rdt);
    if (stat & 1) stat = sys$close ( &fab );
    return stat;
}

Right, but it is different:

See Joe Meadows' FILE utility for an example of how to do it by setting up a $QIO that updates the FIB after setting fib$l_acctl to FIB$M_NORECORD in order to keep your update from being recorded.

Or be lazy (like me) and use Perl:

$ perl -e "utime undef,undef,$ARGV[0];" x.x

or if you envision being lazy in exactly the same way on a regular basis, set up a symbol and use that:

$ touch :== "''perl' -e ""utime undef,undef,$ARGV[0];"""
$ touch x.x

or for VMS versions later than 7.3, you can probably use the CRTL's utime() in your own program.

For ODS2, to set the revdate, which is shown by DIRECTORY as "Revised:" or in DUMP/HEADER as "Revision date:", just use:

$ set file/attr=moddate="time_spec" file_spec
