Re: Removing a specific value from a hash whose keys contains multiple values

[Wiggins d'Anconia]

I am not sure I understand you correctly. Are you referring to a hash which may have a list of values stored with a particular key? Keys by the nature of a hash must be unique, so the hash is changed/deleted from in the same way regardless.

I also didn't understand if you meant clearing the value, or removing the whole key and value pair.

$hash{'key'} = undef;
will clear the value regardless of what it contained, but will leave the key in place.

delete $hash{'key'};
will remove the key and consequently the value that it contained.

If this doesn't resolve the problem please be more specific or give an example.
