Re: Runtime Hash Variable access

First, use code tags here, ok.

I assume you don't use 'use warnings' here? You neeed to use it catch problems like these. Eg you haven't declared any hashes. Should be like this:

%ABCDev = qw /A 1 B 2 C 3/;

But, i'm not sure if the loop will work either. You need to try it again. It might be better to save references into array.

@prods=(\%ABCDev,\%DEFDev,\%GHIDev);
for($i=0;$i<=$#prods;$i++)
{
  @prodkeys = keys %{$prods[$i]};
  print "@prodKeys\n";
}

%ABCDev = qw /A 1 B 2 C 3/; Technically, that defines (assigns to) %ABCDev, but it doesn't declare it. You declare a variable with my, our or use vars. Juerd # { site => 'juerd.nl', plp_site => 'plp.juerd.nl', do_not_use => 'spamtrap' }	[reply]

You are right. Mainly ment that the wanted hash %ABCDev was empty due that assingment happened to scalar and not hash. And that using 'use strict' and 'use warnings' would have caught the mistake. I just don't always think that much about words than meaning (which in some cases can be somewhat obscure due to my lack of attention to words :D).	[reply]

Your code worked fine. Except I had to change the prodKeys to prodkeys :-) Thanks for immediate reply	[reply]
