|A list of one or more item-IDs (separated by spaces) indicating functions to add to the existing built-in functions.
Functions in the function list are no longer available to be called from within FlashBASIC. If the function list is not specified, then a list is presumed to be active. If no list is active, the file-defining the user’s built-in functions is rebuilt to match the list of built-in functions.
