Case-Sensitivity

The list of reserved words returned by the RESERVED function contains some words in all uppercase and some in mixed case. Words all in uppercase are reserved in their entirety. Words in mixed case can be abbreviated to the uppercase portion. For such words, any subset of the word containing the uppercase portion is reserved. For example, one word in the list returned by RESERVED is CODEVERsion. The following are all reserved: codever, codeversi, codeversio, and codeversion. However, codeve is not reserved.
