In Excel and Word 95 and prior editions a weak protection algorithm is used that converts a password to a 16-bit verifier and a 16-byte XOR obfuscation array [1] key. [4] Hacking software is now readily available to find a 16-byte key and decrypt the password-protected document.

This template can be useful when building a sortable table in which a column contains both numbers and text. This template should be applied to every number in the column and should not be used outside of sortable tables. Currently, the template works for numbers between −10 308 and 10 308.

Shared locks can be held by multiple processes at the same time, but an exclusive lock can only be held by one process, and cannot coexist with a shared lock.

A transaction is allowed to write an object if and only if it is holding a write-lock on that object. A schedule (i.e., a set of transactions) is allowed to hold multiple locks on the same object simultaneously if and only if none of those locks are write-locks. If a disallowed lock attempts on being held simultaneously, it will be blocked.
