Re^2: binary parsing

[biohisham]

It seems that the output is different on an Win32 XP system...

perl -le"print length unpack "A", "\n";"
1

Could you please direct me in which side of the documentation neighborhood that this is reported ?

Your quoting is broken. You are doing

>perl -le"print length unpack 'A', \'n';"
1

which is the same as

>perl -le"print length unpack 'A', 'S';"
1

If you fix the quoting, you get the correct result.

>perl -le"print length unpack 'A', qq{\n};"
0

pack says "When unpacking, «A» strips trailing whitespace and nulls".
