The screen blanks and the
word
PHEW!
is
printed, but the X's are not
printed in between. Obviously the value of
C$
is
not being transmitted to the pro-
gram.
RUN
clears ail variables to 0 and ail strings to null before beginning execu-
tion of a program. So
C$
was set to null and that was
what
was printed in the pro-
gram loop
(a
null
is
"nothing";
it
does
not
print nor does it move the cursorl.
Is
there a way to transmit the value of
C$
to the program? Instead of using
RUN.
which
initializes variables, vou can use
GOTO
110 (110 being the line num-
ber of the first line of the program). This does
not
change any variable values.
