Re^3: SNTP pack and unpack

As can be easily demonstrated by

print prototype 'CORE::pack';

pack evaluates the first argument in scalar context. If you supply an array, it turns into the number of its members. You got 1, which is double weird, as it means the array only had one member - you have to supply two things to pack, the template and the list (and, as we have just seen, you can't bundle them in one array).

Hello choroba, Thank you for your time and effort, there are so many things that I do not know. Your answer helped to view the way that pack should be defined. I minor note, it would be easier for me and in general for people who do not know much of Perl to write it like this. `perl -le 'print prototype "CORE::pack"'` Output: `$@` Thanks again for the time and effort, you helped me a lot understanding. Every area that someone has not worked before is always confusing at the beginning. Reference to using CORE::pack, CORE::unpack. Seeking for Perl wisdom...on the process of learning...not there...yet!	[reply] [d/l] [select]
