[aprssig] Perl socket programming

[Andrew Rich]

Thanks

I am looking at how to get the position from a GPS, compacting it and 
sending it over a UDP stream.

I found this works.

print $sock chr(34),chr(0),chr(16) instead of print $sock "ABC"

Is there a way I can contruct an array ?

And then got foreach $value

print $sock chr(val) ?
