| − | where i = 1, ..., n True if the player has entered a phrase that completely matches W(1),...W(n), where n is the number of W(i) which are codes of the vocabulary words.<br />
| |
| − | Here is how the input is matched. After the player types a message and presses Enter, the input line is processed by the interpreter.<br />
| |
| − | Interpreter removes all punctuation marks.<br />
| |
| − | All characters are converted to lowercase.<br />
| |
| − | All sequences of more than one space are replaced with a single space.<br />
| |
| − | Starting with the first word of the input, the interpreter looks up the vocabulary, trying to find the longest character sequence matching the entered.<br />
| |
| − | If the search is unsuccessful, Var(9) is assigned the number of the word in the message that failed to match and the processing ends.<br />
| |
| − | If all the words have been assigned some codes:<br />
| |
| − | * The Interpreter removes from the sequence of codes all zeros (that means all vocabulary words with zero codes are ignored).
| |
| − | * Flag(2) (the user has entered an input line) is set to 1
| |
| − | * Flag(4) ('said' command accepted the user input) is set to 0.<br />
| |
| − | If the sequence of code produced by the interpreter is V(1), V(2),...V(m).
| |
| − | The test is performed as follows:
| |
| − | If Flag(2) = 0 or Flag(4) = 1, return FALSE.
| |
| − | Compare parameters W(i) and codes V(i) as follows:
| |
| − | * if W(i) = 1, it matches any V(i);
| |
| − | * if W(i) = 9999, it matches the whole remaining input i.e. the codes V(i), V(i+1),...V(m).<br />
| |
| − | <br />
| |
| − | Otherwise W(i) should be equal to V(i).<br />
| |
| − | If all elements match, Flag(4) ('said' accepted the user input) is set to 1 and the command returns TRUE. Otherwise, FALSE is returned.

| |
| − | == controller(n); ==
| |
| − |
| |
| − | True if the event with code n has occurred:<br />
| |
| − | * a key with the code n was pressed (set using set_key);
| |
| − | menu item with code n was selected in command menu_input.
