| # | #parameter | If a function or proceedure expects to receive a variable (to which it may point for an address) as a parameter, you cannot substitute a specific address. The pound (#) symbol overrides that feature and tells FutureBasic not to convert the parameter to an address. |
| @ | @varName | Specifies that the operation should use the address of a variable rather than the contents of a variable. This does not work for register variables. |
