Press IReturn) .
(In
this case, you can press
IR
eturn) regardless of the
cursor's position
on
the line, even if it is
in
the middle of the word
PRINT.) No new Error message appears this time. Clear the screen
and
run
the program. The screen should not show any Error
messages.
Another way to
correct
an
Error message is to erase the offending
line.
To
practice this technique, type another line that
ha
s
an
inten-
tional error. This time omit the quotation marks in the
PRI
NT
state-
ment
below, then run and list the program:
60
PRINT
I
ONCE
HAD
A
PROGRAM
CALLED
BOZON
RUN
LIST
An
Error message appears when you press
IR
eturnl and when you try
to
run
and list the program.
To
erase the offending line, simply type
the
line number and press I Returnl :
60
RUN
LIST
Now the program runs and
li
sts without errors, although line 60 does
not contain any instructions.
The
line I
ONCE
HAD
A
PROGRAM
CALLED
BOZON has been erased. Typing the line number and pressing I Returnl
erases a line entirely from the computer's memory. Type the line cor-
rectly
as
shown below:
60
PRINT
"I
ONCE
HAD
A
PROGRAM
CALLED
BOZON"
RUN
PRINT: CREATING BLANK LINES
Inserting a blank line after the poem would make the poem more
readable. Type
in
the following
in
structions to create a blank line
between lines 30 and 40:
35
PRINT
RUN
LIST
When nothing follows the PRINT command, the computer creates a
blank line. Insert another blank line between lines
50
and
60.
Use
55
for the line number and type only the word PRINT after it.
