Thanks for the reply.. But how could I print date for Data::Dumper output in each line as shown in the example?

    First capture the Data::Dumper output in a string, then prepend the timestamp:

    my $message= Dumper $myvar; $message=~ s!^!$timestamp !mg; print $message;

    See the Data::Dumper $Data::Dumper::Pad configuration variable.

    --MidLifeXis

    IMHO, it would make sense to encapsulate everything in a subroutine along the lines of

    use strict; use warnings; sub tprint { my $msg = join $,//'' ,@_; my $tstamp = localtime()." "; $msg =~ s/^/$tstamp/gm; print $msg; } tprint "something\nelse\n";

    BUT to completely replicate the interface of the print function is beyond my Perl skills. I have no idea how one could now provide a file handle to print into file.

[jdporter]: one prog I have has a UI which allows to input a bit mask
[jdporter]: currently it expects the bitmask to be in the form of a hex number, e.g. 0x0101
[jdporter]: but I'd like to let the user specify it as individual bits, i.e. 0b0000000100000001
[jdporter]: there is no bit/binary equivalent of hex, right?
[jdporter]: I guess that the most direct way of doing it is with some magical incantation involving unpack or whatever
