RETURN
RETURN
The
RETURN
sta.tement
i",
used
with
the
GOSUB
statement
to provide a branch and return structure for
TI
BASIC.
Whenever the computer encounters a
RETURN
statement, it
takes
the
program
back
to
the
program
line
immediately
following
the
GOSUB
statement that transferred the computer to
that
particular
subroutine in the first place.
You
can
easily develop programs with
subroutines
which
jump
to
other
subroutines
and
back
again,
if
you
are careful
that
each GOSUB leads the computer
to
a
RETURN
statement.
If,
when
running
a
program.
the
computer
encounters
a
RETURN
statement before performing a
GOSUB
instruction. the program
will terminate with the message "CAN'T DO THAT."
