BOOLEAN PROCEDURE here(comp);
VALUE comp;
STRING comp;
COMMENT: 'Here' determines whether the argument string can be found
beginning at 'pos' in the student answer. Blanks, but nothing
else, may precede the matching word. 'Here' is mostly used
for answers matched in the %NOEXTRA mode;

BOOLEAN PROCEDURE anywhere(comp);
VALUE comp;
STRING comp;
COMMENT: 'Anywhere' determines whether the argument string can be
found anywhere in the student answer after 'pos'. Blanks and
unmatched strings will be bypassed. 'Anywhere' is used in
the %EXTRA mode and in the %NOEXTRA %NOORDER mode.
'Anywhere' will substitute blanks for all characters in
the matched strings. This allows the program (e.g., in the
%NOEXTRA mode) to determine whether there are
any non-blank characters in the student answer. In the
%NOEXTRA mode, his answer will be wrong if any non-blank characters remain;
BEGIN
INTEGER cpos, nextpos;

COMMENT: Since 'anywhere' substitutes blanks for matched parts of the student
answer, the original response must be restored before comparing
it to other target patterns. This restoration is done here;

INTEGER PROCEDURE random;
COMMENT: 'Random' is a number generator which gives a random
number between 0 and 9. The generator will not repeat
itself until after 862 generations;
BEGIN
randno:= randno*10 rem 863;
random:= randno div 87;
END;
PROCEDURE personalize(message);
VALUE message;
STRING message;
COMMENT: 'Personalize' uses the student's firstname in conversational
I/O to give a personal touch to the lessons. To avoid monotony
and to further efficiency, the probability that the message will be
personalized is only .2;
BEGIN

PROCEDURE rightmessage;
COMMENT: 'Rightmessage' is called when a student has
made a correct answer. He is told about this, and the
score is updated. The message to the student is different
depending on whether he succeeds on the fist try or
only after previous fruitless attempts. Random numbers are
used to choose between ten different messages to give
some variation to the conversation;

END;
latescore:= latescore+1;
Newline;
END;
PROCEDURE wrongmessage;
COMMENT: 'Wrongmessage' is called when a student
has made an erroneous answer. He is told about this,
and the lesson statistics are updated. Random numbers
are used to choose between ten different messages in order
provide some variation in the conversation;
BEGIN
lasterrors:= lasterrors+1;
IF firsttry THEN
BEGIN
qcount:= qcount+1;
firsttry:= FALSE;
END;
personalize(wrong[random]);
Newline;
END;
PROCEDURE pause;
COMMENT: Lesson text is given to the student in small portions.
One reason for this is that it is easier to read a little
at a time. Another reason is that display terminals have
a limited screen size. The 'pause' PROCEDURE produces a pause
in the display of text to the student, and she can continue
whenever she has finished examining the displayed material.
To go on, she simply pushes the 'RETURN' key. Normally, this
PROCEDURE is called between each %TEXT or %QUESTION,
but GNOSIS will introduce ADDITIONAL automatic pause points
within large blocks of text or question material.
The teacher can inhibit pauses BETWEEN '%' commands by 'nopause:= TRUE', but
the pauses which GNOSIS inserts in long text blocks cannot be inhibited;

wants to blank the screen on a display terminal).
The effect produced is, of course, terminal dependent;

PROCEDURE extratest;
COMMENT: 'Extratest' will flag and display those parts of the student answer
which WERE matched by the teacher answer pattern IF the
student response contained extra (i.e., superfluous) characters
'Extratest' is called automatically for %RIGHT answers in the
%EXTRA mode. Recall that 'here' scans past leading blanks;

by the student on his very first try since the start of the lesson;

PROCEDURE putaway(question);
COMMENT: If the lesson contained a report-generating command,

<lessonname>.DTA and <lessonname>.SRT, which the teacher can use to improve the
lesson. 'Putaway' writes the unexpected answers in these files;

PROCEDURE tryagain;
COMMENT: Questions output to students who give no answer, a wrong
answer, or an incomplete answer are usually repeated by GNOSIS.
'Tryagain' will output to such students a 'try again' message
which varies according to circumstances. In %NEUTRAL mode,
the message will always be 'Please try again'. Otherwise,
the content of the message depends on the number of times
the student has failed to give a correct response;

the question or who repeatedly fails to give a right answer.
