╦IDS IN SCHOOL HAVE TO LEARN PARTS OF SPEACH SUCH AS NOUNS, VERBS OR PREPOSITIONS. ╘HIS PROGRAM CAN BE USED AS A DRILL IN THE SUBJECT. ┴S SET UP IT'S RATHER BORING AND UNINVITING, BUT YOU CAN DRESS IT UP INTO SOMETHING MORE PLEASANT.
╫HAT YOU CAN LEARN IN THIS SECTION IS ONE OF MANY WAYS TO MAKE SELECTIONS FROM A LIST OF CHOICES, AS WELL AS A SIMPLE DATA SETUP FOR WORD-TYPE INFORMATION.

*** ╔╬╙╘╥╒├╘╔╧╬╙ ***
╔N LINE 200 VARIABLE ╥ IS USED TWICE. ╔T LOOKS SILLY. ╘HE REASON IS DEBUGGING THE GRAPHIC PART. ╨UT ╥┼═ BETWEEN THE TWO FORMULAS. ╫HEN THE CURSOR IS ABLE TO MOVE ROUND AND ROUND THE LIST THE GRAPHIC PART OF THE PROGRAM IS WORKING. ┴T THAT POINT LET THE RANDOM NUMBER ROUTINE ENTER THE PICTURE BY REMOVING THE ╥┼═ARK.
╟RAPHIC CHARACTERS TO TYPE: ╠INE 110 NEEDS ╚╧═┼ AND 23 CURSOR DOWN. ╠INE 120 NEEDS 23 SPACES. ╠INE 180 NEEDS A CLEAR-SCREEN CHARACTER IN QUOTES. ╘WICE IN LINE 210 TYPE ╚╧═┼. ╠INE 250 NEEDS ╚╧═┼. ╠INE 270 GETS CURSOR LEFT TWICE, SAME THING IN LINE 290. ╠INE 310 NEEDS ONE CURSOR-DOWN.
╘HE SCREEN WILL SHOW A WORD IN THE TOP LEFT CORNER. ┴ LIST OF PARTS OF SPEECH WILL BE PRINTED UNDERNEATH. ┴ FLICKERING CURSOR WILL BE ON THE LEFT SIDE OF THE LIST. ╫HEN YOU PRESS THE DOWN-CURSOR KEY IT WILL MOVE DOWN THE LIST AND WRAP-AROUND TO THE TOP. ╨RESS ╥┼╘╒╥╬ TO CHOSE THE PROPER PART OF SPEECH. ╨RESS A STAR TO QUIT.
// PIC: GRAMMAR //
╘HE COMPUTER REPORTS IF YOU'RE CORRECT OR NOT, AND KEEPS THE SCORE OF CORRECT ANSWERS. ┴T THE END THE SCORE IS PRINTED.
═ORE WORDS CAN, AND SHOULD BE ADDED TO THE LIST. ╘HE LIST OF PARTS OF SPEECH SHOULD BE EXPANDED, AS THIS IS ONLY AN ILLUSTRATION YOU CAN TYPE IN QUICKLY.
*** ─┼╘┴╔╠╙ ***
╘HE PARTS OF SPEECH AND THE WORDS ARE TIED TOGETHER. ┘OU CAN SEE NUMBERS TO THE LEFT OF THE WORDS. ╘HEY INDICATE THE PART OF SPEECH NUMBER, SO YOU SEE NUMBER "1" NEXT TO "ZIPPER", SINCE IT IS A NOUN.
╘HIS IS A BIT TRICKY. ┘OU HAVE TO BUILD YOUR LIST IN LINE 330 CAREFULLY, AND NOT CHANGE IT ONCE YOU HAVE CODED THE WORDS, OR YOU'LL HAVE A MESS!
╘HE CURSOR FLICKERS BY BEING PRINTED AND WIPED OFF DURING THE WAIT FOR A KEYPRESS. ┘OU CAN SIMULATE IT BY DOING THE SAME THING ON THE KEYBOARD IN DIRECT MODE: TYPE ">" THEN CURSR-LEFT, SPACE, ">" AGAIN AND SO ON. ╘HAT'S THE WHOLE IDEA.
╘HE CURSOR IS POSITIONED BY PRINTING "HOME" AND P-CHARACTERS FROM THE ─$ WHICH CONTAINS CURSOR DOWN PRINTING CHARACTER. ╨ CHANGES AS YOU PRESS THE CURSOR-DOWN KEY. ╔T IS INCREASED, AND WHEN IT REACHES THE MAXIMUM NUMBER OF PARTS OF SPEECH (╘) WE SET ╨ TO 1 AND REPEAT THE PROCESS ALL OVER.
╘HE POSITION, ╨, RELATIVE TO THE STARTING POSITION ─ (THIRD LINE FROM THE TOP OF THE SCREEN) OF THE CURSOR AT THE TIME YOU PRESS ╥┼╘╒╥╬ TELLS US IMMEDIATELY WHICH ANSWER WAS PICKED. ╙EE LINE 240. ╘HIS USES THE ┴╙├╔╔ FUNCTION TO PICK THE VALUE OF THE FIRST CHARACTER IN A WORD CURRENTLY DISPLAYED. ╥ECALL THAT FIRST CHARACTER IS REALLY A NUMBER (SEE ─ATA LINES).
╫HEN THE TWO NUMBERS MATCH, WE HAVE A CORRECT ANSWER, AND WE SAY SO ON THE RIGHT. ╧THERWISE WE PRINT "NOPE ". ╘HE SPACE INSIDE THE QUOTES IS TO MAKE BOTH MESSAGES EQUAL SIZE FOR EASY BLANKING OUT OF THE LONGER ONE.
*** ╨╥╧╩┼├╘╙ ***
╘HE OBVIOUS ONE IS A GOOD, LONG, CODED LIST OF WORDS. ├ODED, SO THAT NOBODY COULD SNOOP INSIDE THE PROGRAM FOR THE ANSWERS.
┘OU MAY WISH TO PERMIT BOTH UP AND DOWN CURSOR KEYS TO FUNCTION. ╔T WILL BE MORE USEFUL WHEN A LIST OF PARTS OF SPEACH IS LONG.
┘OU COULD BUILD IN A TIME-DELAY, SO THAT INSTEAD OF FLICKERING, THE CURSOR WOULD FLASH. ┬E CAREFUL HERE. ─O NOT ALLOW THE DELAY TO INTERFERE WITH THE USER'S PRESSING A KEY. ╘HE KEYBOARD MUST RESPOND QUICKLY. ╚INT: CHECK IF A KEY IS PRESSED INSIDE YOUR DELAY LOOP. ╔MMEDIATELY EXIT IF IT IS.
