in reply to Initializing an anonymous hash

eval works for me.

use strict; my $hash = {'MONTH' => 'January'}; print $hash->{MONTH} . "\n"; my $hashInitStr = "{'MONTH' => 'January'}"; # This would come from a f +ile my $hash1 = eval $hashInitStr; print $hash1->{MONTH} . "\n"


Z:\Data\Perl> January January Z:\Data\Perl>

Update: Be aware that this has hideous security implications. Also, as Moritz explained to me in reply to Testing error handling that calls "die", there are two forms of eval. But the code given above does what I think you say you want.

    Thanks for your help and for introducing me to eval. I will do some reading.
