in reply to Updating files

AS long as you stick to the text file, there is nothing else than overwriting that file. I suggest to flatten your structure by taking making new hash keys, consisting of a zero-padded number and the keys of the nested hash. You than use these newly generated keys to create a flat database (like BerkeleyDB). This database has a random acces mode, so you can update and add and delete at will.

For the remainder of the code: The translation from AoH to flat access is rather simple. Just concatenate the numbers and keys.

HTH,
