    Have you tried it?? Here goes 

    % perl -012 -e 'print ord $/'
% perl -0012 -e 'print ord $/'

    [download]
    both versions print 10. Watch out though how you cluster your switches, -e has to be last in a cluster or alone!

    Watch out for the special cases of 

    % perl -00   # paragraph mode
% perl -0777 # slurp mode

    Perl treats literals coded into your program with a leading 0 specially. 

    perl -e '$a=017; $b=0x17; print "$a $b\n";'
15 23

    The first number which is treated as octal is 15 in decimal and the second is treated as hexidecimal and so is 23 decimal.
