the
POP
statement
was
executed
,
the
program
is
no
longer
in
the
subroutine
.
If
another
RETURN statement
is
executed,
the
program
will
not
return
to
line
30,
where
the
subroutine
was
called.
The
program
will
return
to
the
line
of
the
previous
GOSUB
statement. Since
there
is
no
other
GOSUB
statement
in
this
program,
a RETURN statement
would
cause
an
error.
A POP
statement
can
also
be used
to
make
the
program
ignore
the
previous
FOR
statement.
When
a
POP
statement
is
executed
within
a FOR/NEXT
loop
,
the
loop
will
not
be repeated.
However
,
an
error
occurs
if
a
NEXT
statement
is
executed
for
that
loop.
