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

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

Thanks for the example :-). You want either 'delete' or 'splice' Depending on whether you want the indexes to be shifted down, see perldoc -f delete and perldoc -f splice. "Deleting an array element effectively returns that position of the array to its initial, uninitialized state. Subsequent

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

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 v
