# Reserved words

The rules for reserved words are:

- Intrinsic function names cannot be dimensioned array names, but can be variable names.

- Special tokens cannot be used as variable names (that is, and, do, else, and so on).

- Any other word can be both an array or variable name.

The list of reserved words are:
