just want to share with other unwary folk the pitfalls
of making an assumption about perl (or anything for that matter)
i tried for the longest time to get something like
the following to work::
foreach $section (keys %board){
for my $a (1..19){
for (1..19){
$board->{"Q1S1"}->[$a]->[$_] and print "\n$a $_";
$board->{"Q1S2"}->[$a]->[$_] and print "\n$a $_";
$board->{"Q2S1"}->[$a]->[$_] and print "\n$a $_";
$board->{"Q2S2"}->[$a]->[$_] and print "\n$a $_";
$board->{"Q3S1"}->[$a]->[$_] and print "\n$a $_";
$board->{"Q3S2"}->[$a]->[$_] and print "\n$a $_";
$board->{"Q4S1"}->[$a]->[$_] and print "\n$a $_";
$board->{"Q4S2"}->[$a]->[$_] and print "\n$a $_";
}
}
}
well, it is supposed to repeat the inner loops several times over right?
for each hashkey, do the following.... etc etc..
if i got rid of the "foreach $section (keys %board){"
the rest would work fine. I was about to yell at you guys about it
when, out of desperation, i tried one last thing :
my $board = \%board; #first line in the whole thing
and it WORKS!!!!
It turns out that a reference to a hash that's created on the 'spur of
the moment' and not explicitly made to refer to a %HASH doesn't work
the same way as a real hash :P
now that i've figured this out, i would love to learn a bit about
/how/ this works.
$board ->{"blah"} is different from $board = \%board; $board->{"blah"}
i think i understand, but would like a clear explanation anyway.
btw- i know it looks like nonsense code, but i cut out some
details in the cut and paste *shrug* - just testing some functions on
an individual basis.....
thanks,
willy
