Examples:
The
GOTO
statement allows you
to
transfer control
backward
or
forward within a program. Whenever the computer reaches a
GOTO
statement.
it
will always jump to the statement with the
specified line-number.
This
is
called an unconditional branch.
In the program
on
the right, line 170 is
an
unconditional branch.
The
computer always skips to line 140
at
this point.
Lme
16U IS
a conditional branch (see
"IF·THEN·ELSE").
The
computer
jumps to line 180 only if
COUNT
and DAYS are equal.
If
you should tell the computer to skip to a line-number that does
not exist in your program, the program
will stop running
and
print
the
message
"BAD
LINE
NUMBER."
Note that the space between the words GO and
TO
is optional.
