Hi Sunita,
As per Uri's suggestions, here's one way to make it work by surrounding the
variable with curly braces
[code]
%hash = ("abc" => 123, "dfg" => 456, "xsd" => 34);
foreach $k (keys %hash){
print "key ${k}:: value $hash{$k}\n";
}
[/code]
[output]
key abc:: value 123
key dfg:: value 456
key xsd:: value 34
[/output]
Hope it helps.
